The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of earth-source hot-pump system with cold accumulating device by ice, it comprises earth-source hot-pump system, heat transfer system of underground heat exchanger 9, Ice Storage Tank 5, air-condition heat exchanger 6, floor coil pipe heating system 2, described earth-source hot-pump system comprises compressor 1, condenser 3, choke valve 7, evaporimeter 4, cross valve 8, described evaporimeter 4 links to each other with Ice Storage Tank 5, air-condition heat exchanger 6, described condenser 3 links to each other with floor coil pipe heating system 2, and described cross valve 8 is installed between condenser 3, evaporimeter 4 and the heat transfer system of underground heat exchanger 9.
Operation principle of the present utility model is as follows:
1, summer cooling: as shown in Figure 2, the utility model summer cooling is circulated by cool cycles, kind of refrigeration cycle, ice-reserving and cooling circulates, and four sub-systems are realized.
(1) cool cycles: enter from condenser 3 hot water out and to carry out heat exchange the heat transfer system of underground heat exchanger 9, heat is discharged.
(2) refrigerant circulation: the cold-producing medium in the earth-source hot-pump system is the heat absorption in the evaporimeter 4, in condenser 3 with cool cycles in water carry out heat exchange, heat is migrated out from heat pump.
(3) ice-reserving circulation: the evaporimeter 4 in the earth-source hot-pump system fills cold to Ice Storage Tank 5, Ice Storage Tank 5 cold-storages.
(4) cooling circulation: evaporimeter 4 or Ice Storage Tank 5 provide indoor cold air distribution to air-condition heat exchanger 6 coolings.Wherein can be divided into again three kinds of cooling mode: A, conventional air-conditioning cooling in the cooling circulation: this moment, Ice Storage Tank 5 was not worked evaporimeter 4 independent coolings; B, air conditioning: this moment, evaporimeter 4 and Ice Storage Tank 5 cooperations were to air-condition heat exchanger 6 coolings; C, single cold-storage cooling: this moment, the earth-source hot-pump system cooling condition was out of service, and air conditioner load is all provided by Ice Storage Tank 5.
In this operational process, heat transfer system of underground heat exchanger 9 can play the effect of conventional cooling tower.When the summer air-conditioning daily load was not too high, earth-source hot-pump system charging employing at night heat transfer system of underground heat exchanger 9 was " cooling tower ".If reasonable in design, the cooling effect of heat transfer system of underground heat exchanger 9 will be much better than the cooling tower in the traditional air-conditioning system.When the air-conditioning daily load was higher, night, the earth-source hot-pump system cold-storage started simultaneously cooling of the cooling condition of earth-source hot-pump system and Ice Storage Tank 5 in the daytime.Design can make evaporating temperature and condensation temperature fluctuation not quite like this, thereby has guaranteed the stable operation of earth-source hot-pump system.
2, Winter heat supply: earth-source hot-pump system constantly is drained into heat in the soil by heat transfer system of underground heat exchanger 9 through the operation of aestivate, and ground temperature raises gradually.Simultaneously, shallow surface constantly absorbs the energy of solar radiation and accumulates in summer as a huge solar thermal collector.Winter, subsurface temperature was relatively high like this, by inputting a small amount of high-grade electric energy, just can carry the low-grade energy in the soil out, after earth-source hot-pump system raising temperature, supplied with 2 heating of indoor floor coil pipe heating system.As shown in Figure 3, winter, the earth-source hot-pump system operational process was comprised of catalyst carrier circulation, refrigerant circulation, three subcycles of confession thermal cycle.By three circulatory systems, geothermal energy " is got ", by indoor floor coil pipe heating system 2 with thermal release out.
