The Gold rotary heat exchang­er is a short cylin­der con­sist­ing of alter­nate­ly flat and cor­ru­gat­ed met­al strips wound on top of each oth­er, form­ing air chan­nels. The rotor rotates in the sup­ply and exhaust air streams, so that the exhaust and sup­ply air pass through the same chan­nels. The mate­r­i­al of the rotor trans­fers heat from the hot­ter extract air to the cool­er sup­ply air.

The water-cool­ing machine Gold Cool­er is built on the basis of a high-effi­cien­cy and low-noise com­pres­sor. ATThe machine is equipped with a hydraulic mod­ule installed at the fac­to­ry. Thanks to this, the cus­tomer was relieved of the need to pur­chase addi­tion­al equip­ment for sup­ply­ing coolant to the heat exchang­er, as well as pay for its com­mis­sion­ing

The silence of the for­est, the fresh wind from the riv­er, the bright col­ors of the sun­ny morn­ingThe best stress reliev­ers. Real­iz­ing this, many peo­ple today pre­fer to live in the bosom of nature, in their own cot­tage, equipped with a reli­able cli­mate sys­tem that pro­vides com­fort­able indoor air para­me­ters.

In win­ter and dur­ing the tran­si­tion­al peri­od (spring and autumn), the cli­mate sys­tem of a coun­try house in cen­tral Europe pro­vides heat­ing, and in sum­mer, in the heat, air cool­ing- the tem­per­a­ture in the rooms is con­stant­ly kept at the lev­el of 22–24C. In addi­tion, the range of tasks solved by a mod­ern cli­mate sys­tem nec­es­sar­i­ly includes forced ven­ti­la­tion of rooms. This process involves the sup­ply of fresh air from the street to the liv­ing rooms and util­i­ty rooms (at the rate of at least 3m3/h per 1m2 liv­ing space), as well as remov­ing pol­lut­ed air, excess mois­ture and odors from the house.

The fruits of evolution

From time immemo­r­i­al, stove heat­ing has been used for heat­ing and orga­niz­ing air exchange in coun­try estates. A well-heat­ed stove retained heat for a long time and pro­vid­ed space heat­ing in cold weath­er. Pol­lut­ed air left the house through the chim­ney, sup­port­ing the com­bus­tion of fuel dur­ing the fur­naces, and fresh air entered the rooms through leaks in win­dows and doors. More­over, our grand­fa­thers were not seri­ous­ly wor­ried about even small val­ues ​​of the fuel effi­cien­cy- fire­wood or coal, no tem­per­a­ture fluc­tu­a­tions that reached + ‑2.5 between fire­box­esC and more (up to + ‑15C!), nei­ther pol­lu­tion of the house with fuel, nor pen­e­tra­tion into the premis­es of prod­ucts of incom­plete com­bus­tion- car­bon monox­ide andt.n. Cool­ing the air in the rooms was not even thought of then.

How­ev­er, in recent years, tech­no­log­i­cal progress has rad­i­cal­ly changed the “sub­ur­ban” way of life. The require­ments for com­fort have changed, new con­struc­tion tech­nolo­gies have appeared, and after this, new micro­cli­mate tech­nolo­gies, hith­er­to unknown in a coun­try estate, have become wide­spread.

The desire to get rid of the short­com­ings of stove heat­ing that are obvi­ous to a mod­ern city dweller forced devel­op­ers to look for more advanced heat­ing sys­tems. To pro­tect against the win­ter cold, coun­try hous­es began to be equipped with water radi­a­tor heat­ing sys­tems (sim­i­lar to those used in urban high-rise build­ings), as well as water-heat­ed floors. This tech­ni­cal solu­tion turned out to be very appro­pri­ate, since it ensures the con­stan­cy (stor­age through­out the day) of the val­ue set by the user with an accu­ra­cy of + ‑1C and uni­for­mi­ty of air tem­per­a­ture in rooms (0.5 C per meter of height) regard­less of the weath­er con­di­tions out­side. In addi­tion, radi­a­tor heat­ing with under­floor heat­ing made it pos­si­ble to heat a coun­try house with­out human inter­ven­tion dur­ing the entire heat­ing sea­son (which is impor­tant, because in cen­tral Europe it is nec­es­sary to heat 8–9months of the year).

At first, they also tried to orga­nize the ven­ti­la­tion of cot­tages by anal­o­gy with urban mul­ti-storey build­ings, equip­ping them with nat­ur­al exhaust. How­ev­er, this approach unex­pect­ed­ly turned out to be a dead end. The use of dou­ble-glazed win­dows, doors with a her­met­ic porch and oth­er mod­ern build­ing mate­ri­als and mech­a­nisms, of course, led to a sig­nif­i­cant reduc­tion in heat loss in coun­try hous­es, made them more aes­thet­ic. But due to the lack of gaps in the bind­ings of the frames and in oth­er build­ing struc­tures, nat­ur­al ven­ti­la­tion turned out to be inef­fec­tive. Fight­ing the stuffi­ness and musti­ness of the air with the help of vol­ley ven­ti­la­tion (open­ing win­dows in all rooms at the same time for 10–20 min­utes) is uncom­fort­able because of drafts that are poor­ly tol­er­at­ed by the elder­ly and chil­dren, and also for safe­ty rea­sons. More­over, the decrease in the qual­i­ty of the air envi­ron­ment due to a sharp increase in the num­ber of vehi­cles and for­est fires in dry sum­mers has gen­er­al­ly called into ques­tion the pos­si­bil­i­ty of reg­u­lar­ly open­ing win­dows.

Thus, the urgent need to use mechan­i­cal ven­ti­la­tion sys­tems in a mod­ern coun­try house was real­ized. After all, they are able to pro­vide year-round high-qual­i­ty pre-clean­ing, heat­ing or cool­ing and com­fort­able dis­tri­b­u­tion of sup­ply air in the premis­es, as well as the removal of pol­lut­ed air and odors.

Energy saving and comfort

Of course, the wide­spread intro­duc­tion of new cli­mate sys­tems in coun­try life does not always go with­out a hitch. Today, on aver­age, the cli­mate sys­tem accounts for 30 to 70% of the total ener­gy con­sump­tion of a cot­tage, which in mon­e­tary terms (util­i­ty pay­ments) for a house with an area of ​​300–500m2 trans­lates into sev­er­al thou­sand euros per year. Andthis is not the lim­it- the cost of oper­at­ing the sys­tem is con­stant­ly increas­ing as ener­gy prices rise. In addi­tion, gas is usu­al­ly sup­plied to a coun­try house in a strict­ly lim­it­ed vol­ume.- the sup­ply gas pipeline often does not allow you to get more than 100–150kW of ther­mal pow­er. BUTin some cas­es this is not enough even for a rel­a­tive­ly small estate. After all, dur­ing the peri­od of max­i­mum ener­gy con­sump­tion, heat is required for heat­ing radi­a­tors, as well as under­floor heat­ing, ven­ti­la­tion and hot water sys­tems, not to men­tion pool heat­ing and oth­er needs. Occa­sion­al­ly, the miss­ing kilo­watts can be “gained” through the use of elec­tric­i­ty, but this, of course, leads to an increase in oper­at­ing costs.

ATIn the con­text of a fair­ly tight lim­it and high prices for ener­gy resources, the instal­la­tion of tra­di­tion­al boil­er and ven­ti­la­tion equip­ment in a coun­try house turns out to be a waste­ful event, and often prac­ti­cal­ly unre­al­iz­able. To reduce ener­gy costs, it is nec­es­sary to use some­what more expen­sive, but eco­nom­i­cal equip­ment when com­plet­ing the cli­mate sys­tem.- air han­dling units with heat recov­ery, as well as high­ly effi­cient boil­er equip­ment.

Mod­ern ener­gy-effi­cient equip­ment for heat­ing and ven­ti­la­tion usu­al­ly oper­ates inde­pen­dent­ly in coun­try hous­es, using “advanced” indi­vid­ual con­trol algo­rithms. But spe­cial automa­tion func­tions allow you to inte­grate this tech­nique into the “smart home” sys­tem. Despite some increase in the cost of the air con­di­tion­ing project (from 30%), this leads to an addi­tion­al improve­ment in its ener­gy-sav­ing prop­er­ties, sim­pli­fies the pro­ce­dure for cre­at­ing a cli­mate and improves the safe­ty of engi­neer­ing sys­tems. More­over, they are con­trolled both from indi­vid­ual con­trol pan­els of the instal­la­tions, and from a sin­gle con­trol pan­el of an inte­grat­ed sys­tem. It is enough for the user to set the desired tem­per­a­ture in a par­tic­u­lar room, after which the “smart home” itself will choose the opti­mal mode of oper­a­tion of heat­ing, ven­ti­la­tion and air con­di­tion­ing. In case of emer­gen­cies (for exam­ple, in cas­es of heat­ing leak­age, ven­ti­la­tion fail­ure or sim­ply dirty air fil­ters), the SMS mes­sag­ing sys­tem will instant­ly send infor­ma­tion about the prob­lem to the owner’s mobile phone, as well as to the emer­gency tech­ni­cal or med­ical assis­tance ser­vice.

Object example

An exam­ple of the imple­men­ta­tion of a mod­ern ener­gy-effi­cient cli­mate sys­tem in a coun­try house may well serve as a cli­mate con­trol sys­tem in a two-sto­ry cot­tage with an area of ​​450m2. It is locat­ed in the vil­lage of Lesnye Dali near world, locat­ed on the Min­sk high­way. The com­plex of equip­ment serves all the main and aux­il­iary premis­es of this mod­ern coun­try house. ATliv­ing area (two bed­rooms, a liv­ing room, a din­ing room, a fire­place room and an office), as well as in the kitchen, the tem­per­a­ture is auto­mat­i­cal­ly main­tained at 22–24C, 1–7‑fold air exchange is car­ried out. Along with oth­er engi­neer­ing equip­ment, cli­mate tech­nol­o­gy is inte­grat­ed into the “smart home” sys­tem. The facil­i­ty was built by TRIA COMM in coop­er­a­tion with RM VENT (deliv­ery of an ener­gy-effi­cient ven­ti­la­tion sys­tem). The cost of imple­ment­ing an engi­neer­ing solu­tion- approx­i­mate­ly 115 for 1m2 the total area of ​​the cot­tage.

Heating system

Boil­er room area 6m2 (ceil­ing height- 2.6m) is locat­ed on the first floor, in the right wing of the coun­try house, next to the garage. It has two exits.- one out­side, the sec­ond in the garage. The boil­er room is sep­a­rat­ed from the lat­ter by a spe­cial sound­proof fire­proof door. For nat­ur­al light in the out­er wall, two win­dows with an area of ​​0.8m2. Air extrac­tion is car­ried out using a low-noise fan EBERLE (Swe­den). The floor of the room has a slope towards the sew­er drain. All equip­ment is con­nect­ed to the com­mon ground loop of the cot­tage and placed in the boil­er room in such a way that it is eas­i­ly acces­si­ble for main­te­nance and repair.

ATthe boil­er room is equipped with a Logano G315 heat gen­er­a­tor man­u­fac­tured by BUDERUS (Ger­many), hav­ing a ther­mal capac­i­ty of 105kW. The boil­er runs on main nat­ur­al gas. ATIn the com­bus­tion cham­ber of the boil­er, a three-way prin­ci­ple of flue gas move­ment is used, which, in com­bi­na­tion with a devel­oped heat exchange sur­face and ther­mal insu­la­tion of the boil­er block, ensures a fair­ly effi­cient use of the ener­gy released dur­ing fuel com­bus­tion (the effi­cien­cy reach­es 95%). Fur­nace mate­r­i­al- gray cast iron- guar­an­tees high resis­tance to cor­ro­sion and long ser­vice life of the boil­er (resource- 80 years). The boil­er can oper­ate in low tem­per­a­ture mode- the “Ther­mostream” tech­nol­o­gy imple­ment­ed in its design pre­vents the for­ma­tion of caus­tic con­den­sate on the fur­nace sur­faces when the tem­per­a­ture of the water return­ing to the device (return line) drops to room tem­per­a­ture, and also helps to increase the effi­cien­cy of the heat­ing sys­tem and reduce the emis­sion of harm­ful sub­stances.

For the most effi­cient com­bus­tion of fuel, the boil­er is equipped with a mod­u­lat­ing two-stage gas burn­er K3x‑G, 1″ com­pa­ny KRTING (Ger­many) per­for­mance 24–149kW. This burn­er pro­vides a smooth tran­si­tion from one pow­er lev­el to anoth­er, reg­u­lates the mix­ing of air with fuel with high accu­ra­cy, main­tains oper­abil­i­ty at gas pres­sure in the main gas pipeline from 5 mbar, is equipped with a safe­ty and fault detec­tion sys­tem (self-test­ing).

The boil­er is con­trolled by an ener­gy-effi­cient micro­proces­sor automa­tion sys­tem Logo­mat­ic 4211 (BUDERUS). It sets the algo­rithm for the oper­a­tion of four load cir­cuits (radi­a­tors, under­floor heat­ing, an addi­tion­al heat­ing water heater for ven­ti­la­tion and hot water sup­ply) with mix­ers accord­ing to its own pro­grams. The entire boil­er pip­ing was made using MEIBÖS (Ger­many) mod­u­lar quick assem­bly groups, the use of which made it pos­si­ble to elim­i­nate design errors; reduce time, as well as improve the aes­thet­ics and qual­i­ty of instal­la­tion; Sim­pli­fy equip­ment main­te­nance.

Part of the pow­er gen­er­at­ed by the boil­er is used to heat domes­tic hot water. To do this, the device is equipped with a 300-liter ver­ti­cal stor­age boil­er Logalux ST300. The boil­er is locat­ed in the boil­er room and is capa­ble of sup­ply­ing up to 1355 liters of water heat­ed to 45C (coil pow­er- 55.2kW, heat­ing cir­cuit tem­per­a­ture- 80FROM). As with most devices of this kind on the mar­ket, all inte­ri­or sur­faces of the Logalux ST300 that come into con­tact with water are ther­mal­ly glazed and a mag­ne­sium anode is used to increase cor­ro­sion resis­tance. The body of the boil­er is equipped with a lay­er of ther­mal insu­la­tion made of rigid polyurethane foam.- so heat loss­es are min­i­mized.

ATIn win­ter, most of the heat pro­duced by the boil­er is used for space heat­ing and sup­ply air heat­ing. ATIn the cot­tage, a two-pipe col­lec­tor-beam wiring dia­gram for the radi­a­tor heat­ing sys­tem with pump cir­cu­la­tion of the coolant was used. ATele­gant low-iner­tia pan­el radi­a­tors BUDERUS with bot­tom con­nec­tion are used as heat­ing devices. The floor water heat­ing sys­tem is made accord­ing to the “wet instal­la­tion” method: pipeline sec­tions are laid in a snake in the thick­ness of the con­crete screed. For lay­ing the pipelines of the floor heat­ing sys­tem and the heat­ing sys­tem, a durable cop­per pipe man­u­fac­tured by KME (Ger­many) was used.

Ventilation and air conditioning system

The ven­ti­la­tion cham­ber is locat­ed on the upper lev­el of the cot­tage, in the attic. More­over, the area of ​​the ven­ti­la­tion cham­ber is only 5.5m2and the ceil­ing height- 2.5m. Vthe room has all the com­mu­ni­ca­tions nec­es­sary for the oper­a­tion of the ven­ti­la­tion sys­tem: pow­er sup­ply, coolant from the boil­er room, drainage. The equip­ment is installed in such a way that it has unhin­dered access for main­te­nance and repair.

ATas the basic equip­ment of the ven­ti­la­tion cham­ber, a monoblock air-prepar­ing unit Gold man­u­fac­tured by PM-LUFT (Swe­den) was used. It arrived at the facil­i­ty in full fac­to­ry readi­ness (that is, it was equipped with all the nec­es­sary equip­ment and test­ed by the man­u­fac­tur­er, for instal­la­tion it only remained to sup­ply pow­er, con­nect air ducts and drainage).

The Gold unit is equipped with a rotary heat exchang­er, which makes it pos­si­ble to use the heat and cool­ness dis­charged into the envi­ron­ment with the exhaust air flow to heat or cool the sup­ply air. In addi­tion, the heat exchang­er pro­vides a min­i­mum humid­i­ty (30%) of the sup­ply air even under the most unfa­vor­able con­di­tions out­side (dry frosty weath­er), which made it pos­si­ble to refuse the use of spe­cial humid­i­fiers in the cot­tage.

Fresh air is tak­en into the unit through the wall grille and the sup­ply air duct; cleared of dust; heat­ed or cooled depend­ing on the time of year due to the ener­gy of the exhaust air returned to the unit from the cot­tage rooms through the net­work of return air ducts. Then the sup­ply air enters the main air duct. Used exhaust air is removed from the unit via a roof extrac­tor.

To pre­heat the sup­ply air in the cold sea­son, a hot water heater with an anti-freeze sys­tem is installed on the main sup­ply air duct behind the Gold unit, which is con­nect­ed to the boil­er. Due to the high effi­cien­cy of the heat exchang­er of the Gold unit (up to 85%), as well as auto­mat­ic con­trol of flow rates and air tem­per­a­ture, the pow­er of the select­ed reheater turned out to be almost 10 times low­er than the pow­er of the heater, which would have to be used in a clas­si­cal direct-flow ven­ti­la­tion sys­tem of the same char­ac­ter­is­tics. It is char­ac­ter­is­tic that the installed heater is used only a few days a year.- the need for its action is felt only at out­door tem­per­a­tures below ‑5 S. Ithis is despite the fact that the Gold unit pro­vides 100% air sup­ply and extract air with­out the use of recir­cu­la­tion.

FROMIn order to addi­tion­al­ly cool the air sup­plied to the premis­es in sum­mer, the sup­ply air duct behind the air heater has a liq­uid heat exchang­er con­nect­ed to the Gold Cool­er (PM-LUFT) chiller, which is installed direct­ly in the ven­ti­la­tion cham­ber. This allowed the own­er of the cot­tage to avoid installing many split sys­tems. The refrig­er­a­tion machine is stan­dard­ly equipped with a hydraulic mod­ule, thanks to which it was pos­si­ble to refuse to pur­chase addi­tion­al pump­ing equip­ment and an accu­mu­la­tor tank to ensure the cir­cu­la­tion of the coolant. The chiller con­denser is built into the exhaust air duct, as a result, it was not nec­es­sary to mount the equip­ment on the out­er wall of the build­ing to the detri­ment of the archi­tec­tur­al appear­ance of the coun­try house.

The Gold unit locat­ed with­in the ven­ti­la­tion cham­ber, sup­ply and exhaust air ducts, as well as all heat exchange equip­ment with pip­ing ele­ments are con­cen­trat­ed near the end wall, which has a width of approx­i­mate­ly 2m. There is no lev­el­ing sec­tion of the air duct and a silencer at the out­let of the unit;. Such a ratio­nal lay­out of the sys­tem was made pos­si­ble due to the use of spe­cial axi­al-radi­al fans in the ven­ti­la­tion unit. Thanks to the spe­cial impeller pro­file, they are char­ac­ter­ized by a low lev­eled air veloc­i­ty at the out­let. ATas a result, a low noise lev­el is ensured, it becomes pos­si­ble to sig­nif­i­cant­ly reduce the con­struc­tion length of the unit with­in the ven­ti­la­tion cham­ber and con­nect the fit­tings (elbows) of the air ducts direct­ly to the unit, with­out the use of air­flow equal­iz­ing sec­tions (they would be required to reduce pres­sure loss­es when the cus­tomer choos­es tra­di­tion­al ven­ti­la­tion units with cen­trifu­gal fans).

The con­trol com­put­er of the Gold unit is built direct­ly into the unit hous­ing. For dia­logue with the user, the device is equipped with a mul­ti­lin­gual remote con­trol, on the illu­mi­nat­ed liq­uid crys­tal screen of which text for­mu­la­tions of com­mands are dis­played. To acti­vate them, you just need to press the selec­tion and input keys. In addi­tion, dozens of use­ful func­tions pro­vid­ed by the man­u­fac­tur­er can be imple­ment­ed, such as a free cool­ing mode by increas­ing the inflow of out­door air with­out the par­tic­i­pa­tion of a refrig­er­a­tion machine (“night cool­ness”), a smoke pro­tec­tion mode (in the event of a fire, the unit removes smoke from the rooms, pro­vid­ing clear­ing of escape routes from smoke) peo­ple from the premis­es). The own­er can receive infor­ma­tion about the state of the unit, as well as reg­u­late its actions remote­ly- via the Inter­net or SMS-mes­sages.

Dur­ing oper­a­tion, the automa­tion of the ven­ti­la­tion unit con­stant­ly adapts to the oper­at­ing con­di­tions, adjust­ing the tem­per­a­ture and the total flow of fresh air sup­plied to the premis­es flex­i­bly, with­out unnec­es­sary ener­gy con­sump­tion, and con­stant­ly mon­i­tor­ing itself with the help of numer­ous sen­sors. Automa­tion made it pos­si­ble to inte­grate Gold into the “smart home” sys­tem, cre­at­ed on the basis of the AMX proces­sor (USA), and to real­ize the abil­i­ty to quick­ly and smooth­ly con­trol the tem­per­a­ture and air exchange rate indi­vid­u­al­ly for each room. More­over, due to the fact that the automa­tion of the instal­la­tion “under­stands” almost all dis­patch­ing pro­to­cols, the “smart home” sys­tem can devel­op over time.

Out­side the ven­ti­la­tion cham­ber there are net­works of sup­ply and exhaust air ducts, like arter­ies and veins pen­e­trat­ing a coun­try house. The wiring of sup­ply and exhaust air ducts is made behind a false ceil­ing and false walls of the cot­tage. The net­works con­sist of round heat-insu­lat­ed met­al pipes. ATSTIFAB FAREX devices (Swe­den) were used as final dis­tri­b­u­tion ele­ments. A char­ac­ter­is­tic fea­ture of the air dis­trib­u­tors of this com­pa­ny is the abil­i­ty, with a tem­per­a­ture dif­fer­ence between the floor and the ceil­ing of 10C to ensure the main­te­nance of air speed in the work­ing area of ​​0.2m/s. BUTthis means that the inhab­i­tants of the room will not feel drafts. Iris valves are installed in front of the air dis­tri­b­u­tion devices on the sup­ply ven­ti­la­tion ducts. They pro­vide smooth reg­u­la­tion of the vol­ume of fresh air sup­plied to the premis­es.

To elim­i­nate smoke smells from burn­ing peat­lands and oth­er air pol­lu­tion, a bypass line with a car­bon fil­ter with a large active sur­face (PM-LUFT) is pro­vid­ed in the ven­ti­la­tion sys­tem on the inlet. The line is con­nect­ed, depend­ing on the sit­u­a­tion, in one of two modes- man­u­al­ly (using a remote con­trol) or auto­mat­i­cal­ly, by a sig­nal from a car­bon monox­ide sen­sor.

Conclusion

The use of ener­gy effi­cient equip­ment made it pos­si­ble not to con­nect 20kW of addi­tion­al elec­tric pow­er (for which it would be required to pay about 7000) and reduce the annu­al costs of oper­at­ing the cli­mate sys­tem by dozens of times. The inte­gra­tion of automa­tion of boil­er, ven­ti­la­tion equip­ment and the cen­tral proces­sor of the “smart home” sys­tem made it pos­si­ble to indi­vid­u­al­ly con­trol the tem­per­a­ture in each room, and also increased the ener­gy sav­ing of the instal­la­tion due to the coor­di­nat­ed “con­flict-free” use of ven­ti­la­tion and heat­ing sys­tems of a coun­try house.
