Below with reference to Fig. 1～Fig. 4 the action of the air-conditioning system 101 of present embodiment is described.At this, Fig. 2 is the tephigram of the action of expression air-conditioning system 101.Fig. 3 is the pressure-enthalpy chart of the action of expression air-conditioning system 101.Fig. 4 is the air line chart of the action of expression air-conditioning system 101.
At first, 145 startings of thermophore circulating pump circulate thermophore in thermophore loop 104.Then, make compressor 121 startings of heat source unit 102.So the low pressure refrigerant (with reference to the some Rc shown in Fig. 1～Fig. 3) that is drawn in the compressor 121 is discharged by compressor 121 compression backs, becomes the cold-producing medium (with reference to the some Ri shown in Fig. 1～Fig. 3) of HTHP.The cold-producing medium of this HTHP flows in thermophore-refrigerant heat exchanger 122 thermophore is heated, and itself is cooled and becomes the cold-producing medium (with reference to the some Ro3 shown in Fig. 1～Fig. 3) of cryogenic high pressure.The cold-producing medium that should be in thermophore-refrigerant heat exchanger 122 be cooled because of the heating of thermophore becomes the cold-producing medium (with reference to the some Re3 shown in Fig. 1～Fig. 3) of the gas-liquid two-phase state of low-temp low-pressure after by expansion mechanism 123 decompressions.The cold-producing medium of this gas-liquid two-phase state by thermals source such as water or outdoor air heating back evaporation, becomes the gaseous refrigerant (with reference to the some Rc shown in Fig. 1～Fig. 3) of low-temp low-pressure in heat source side heat exchanger 124.And the gaseous refrigerant of this low-temp low-pressure sucks in the compressor 121 again.
At this, the thermophore of circulation flows into thermophore-refrigerant heat exchanger 122 (with reference to the some Wi3 shown in Fig. 1, Fig. 2 and Fig. 4) from the thermophore inlet in thermophore loop 104, in thermophore-refrigerant heat exchanger 122, carry out heat exchange with the high-temperature high-pressure refrigerant of discharging, thereby be heated (with reference to the some Wo shown in Fig. 1, Fig. 2 and Fig. 4) by compressor 121 compression backs.And, heating medium for high temperature after being heated in thermophore-refrigerant heat exchanger 122 flows into the radiator of radiator 141 with among the heat exchanger 141a, the heat of thermophore is emitted (particularly to indoor, radiator is heated with the room air around the heat exchanger 141a), thermophore itself is cooled and temperature reduction (for example shown in Figure 2, as to drop to about 65 ℃ from about 70 ℃).At this moment, room air (with reference to some RA shown in Figure 4) is heated to the state of some SA1 shown in Figure 4 in heat exchanger 141a at radiator.
Then, the thermophore that flows out with heat exchanger 141a from radiator flows into the convector of fan convection type warmer 142 with the heat exchanger 142a, the heat of thermophore is emitted (particularly to indoor, to heating with the room air that fan 142b supplies with) by convector, thermophore itself is cooled and temperature reduction (for example shown in Figure 2, as to drop to about 55 ℃ from about 65 ℃).At this moment, room air (with reference to some RA shown in Figure 1) by convector with heat exchanger 142a as air supply SA1 ' (with reference to Fig. 1) to indoor supply.
Then, use the pipe arrangement 143a with the ground heating of the thermophore inflow surface heating installation 143 of heat exchanger 142a outflow from convector, the heat of thermophore is emitted (particularly to indoor, ground is heated with pipe arrangement 143a by the ground heating), thermophore itself is cooled and temperature reduction (for example shown in Figure 2, as to drop to about 40 ℃ from about 55 ℃).
Then, use the heat exchanger 144a with the outdoor air heating of heat-exchange device 144 with the thermophore inflow outdoor air heating of pipe arrangement 143a outflow from the ground heating, utilize the heat of thermophore to heat with air to supplying to indoor ventilation by feeder 103, thermophore itself is cooled and temperature reduction (for example shown in Figure 2, as to drop to about 5 ℃ from about 40 ℃).At this moment, ventilation is heated to the state (being about 20 ℃ in Fig. 4) of some SA3 shown in Figure 4 with heat exchanger 144a by the outdoor air heating with air (with reference to the some OA shown in Fig. 4 ,-10 ℃ approximately).On the other hand, the temperature of room air RA is heated to about 20 ℃ (with reference to the some RA shown in Fig. 4) by the heating running that radiator 141, fan convection type warmer 142 and ground heating installation 143 carry out.Therefore, even use the ventilation after heat exchanger 144a heats to mix with room air RA to indoor supply with air by this outdoor air heating, the temperature of room air also changes hardly.
And, flow into (with reference to the some Wi3 shown in Fig. 1, Fig. 2 and Fig. 4) thermophore-refrigerant heat exchanger 122 with the thermophore that heat exchanger 144a flows out again by thermophore circulating pump 145 from the outdoor air heating.
(3) feature of air-conditioning system

But, in the air-conditioning system 101 of present embodiment, have outdoor air heating heat-exchange device 144, therefore, when carrying out heating of house, as shown in Figure 4, can to by feeder 103 after the outdoor air OA heating of the conduct of indoor supply ventilation with air, again with its as air supply SA3 to indoor supply, therefore, can prevent that the ventilation to indoor supply causes cold wind with air in order to carry out indoor ventilation, can improve indoor comfort.
(B)
In existing air-conditioning system 901, because thermophore loop 904 does not have ground heating installation 143 and outdoor air heating heat-exchange device 144, therefore, as Fig. 2, Fig. 3 and shown in Figure 5, heated thermophore circulates in thermophore loop 104 by carrying out heat exchange with cold-producing medium in thermophore-refrigerant heat exchanger 122, become the state of a Wi1 from the state of a Wo, and return again in thermophore-refrigerant heat exchanger 122.Meanwhile, as shown in Figures 2 and 3, cold-producing medium circulates in refrigerant loop 120, from the state of the some Rc of compressor 121 suction sides successively through the state of the some Ri corresponding with a Wo, with the state of the corresponding some Ro1 of some Wi1, put the state of Re1, and be drawn into again in the compressor 121.At this, as shown in Figure 3, the COP (is benchmark with the evaporation side) of the heat source unit 102 in the existing air-conditioning system 901 is values (=Δ h1/ Δ hc) that the value of the evaporation side enthalpy difference Δ h1 in the kind of refrigeration cycle of an an an an a Rc → Ri → Ro1 → Re1 → Rc and the value of the enthalpy difference Δ hc of the consumption of power that is equivalent to compressor 121 are divided by and are obtained.
On the other hand, in the air-conditioning system 101 of present embodiment, thermophore loop 104 has ground heating installation 143 and outdoor air heating heat-exchange device 144, and be connected with thermophore-refrigerant heat exchanger 122, the thermophore that makes heating in thermophore-refrigerant heat exchanger 122 is successively to radiator 141, fan convection type warmer 142, ground heating installation 143, the outdoor air heating is supplied with heat-exchange device 144, therefore, as Fig. 1, Fig. 2 and shown in Figure 3, heated thermophore circulates in thermophore loop 104 by carrying out heat exchange with cold-producing medium in thermophore-refrigerant heat exchanger 122, become the state of a Wi3 from the state of a Wo, and return again in thermophore-refrigerant heat exchanger 122.Meanwhile, as shown in Figures 2 and 3, cold-producing medium circulates in refrigerant loop 120, from the state of the some Rc of compressor 121 suction sides successively through the state of the some Ri corresponding with a Wo, with the state of the corresponding some Ro3 of some Wi3, put the state of Re3, and be drawn into again in the compressor 121.Therefore, in radiator 141, fan convection type warmer 142 and ground heating installation 143, can utilize the heat of the heating medium for high temperature after in thermophore-refrigerant heat exchanger 122, being heated, with in the heat-exchange device 144, can utilize the heat that in radiator 141, fan convection type warmer 142 and ground heating installation 143, cools off the thermophore of back (with reference to the some Wi2 shown in Fig. 1 and Fig. 2) in the outdoor air heating to indoor heat release.At this, because it is lower than room air (representing with RA among Fig. 1) to the ventilation of indoor supply with the temperature of air (representing with OA among Fig. 1) by feeder 103, therefore, can utilize in radiator 141, fan convection type warmer 142 and ground heating installation 143 to indoor heat release and cooled thermophore heats it.And, be used for after the thermophore that the outdoor air heating is heated with air with the ventilation of the indoor supply of heat-exchange device 144 subtends is heating with air ventilation and further cooling off (with reference to the some Wi3 shown in Fig. 1 and Fig. 2), turning back in thermophore-refrigerant heat exchanger 122.Like this, in air-conditioning system 101, will be in radiator 141, fan convection type warmer 142 and ground heating installation 143 heat release and the thermophore that cools off is supplied with heat-exchange device 144 to the outdoor air heating, the ventilation that is used for the indoor supply of subtend is heated with air, therefore, compare with air-conditioning system 901, can strengthen the temperature difference (that is the thermophore temperature and the temperature difference of putting the thermophore temperature under the Wi3 state under the some Wo state) at the place, gateway of thermophore-refrigerant heat exchanger 122.Thus, as shown in Figure 3, because the COP (is benchmark with the evaporation side) of the heat source unit 102 in the air-conditioning system 101 of present embodiment is values (=Δ h3/ Δ hc) that the value of the evaporation side enthalpy difference Δ h3 in the kind of refrigeration cycle of an an an an a Rc → Ri → Ro3 → Re3 → Rc and the value of the enthalpy difference Δ hc of the consumption of power that is equivalent to compressor 121 are divided by and are obtained, so and existingly do not have outdoor air heating and compare the COP raising with the air-conditioning system 901 of heat-exchange device 144.Especially in the air-conditioning system 101 of present embodiment, except that outdoor air heats with also having ground heating installation 143 heat-exchange device 144, therefore, compare, can further strengthen the temperature difference and the COP at the place, gateway of thermophore-refrigerant heat exchanger 122 with existing air-conditioning system 901.
