In addition, in air conditioning hot supplies hybrid system 100, operating halted state is in hot water supply unit 303
In the case of, control unit 15 controls solenoid valve 52 to close.Specifically, the stream of refrigerant of the control unit 15 in refrigeration operation
In dynamic, closing control is carried out to being set to the solenoid valve 52 of upstream side of heat exchanger 31.
As described above, air conditioning hot supplies hybrid system 100 in the case where load side unit is in operating halted state,
Control unit 15 proceeds as follows action, i.e.,：The flowing of the refrigerant in refrigerant circuit 340 is switched via four-way valve 14
Flowing during for refrigeration operation completely closes expansion valve 51, and solenoid valve 52 is controlled to close.Therefore, according to air conditioning hot
Hybrid system 100 is supplied, such as even if expansion valve 51c situation of foreign matter etc. is being bitten such as expansion valve 51c can not hide completely
In the case of the flowing of disconnected refrigerant, the flowing of refrigerant can be also interdicted by closing control solenoid valve 52.That is, according to swollen
The state of swollen valve 51c, the refrigerant of low temperature can flow, but can utilize to the hot water supply unit 303 in operating halted state
The solenoid valve 52 of closing control is performed to interdict the flowing of refrigerant, so as to prevent along the primary circuit of heat exchanger 31
37 flowing waters are freezed.
In addition, it is controlled in a manner of solenoid valve 52 being closed by only in the exception of expansion valve 51c when.In hot water supply
The refrigerant piping 350 of the upstream side (the refrigeration flow direction (direction of arrow) of refrigerant) of the heat exchanger 31 of unit 303
Temperature sensor (not shown) is set.It is sent from the temperature information that temperature sensor detects as signal to control unit 15.
When hot water supply unit 303 is in operating halted state, expansion valve 51c can not interdict the flowing of refrigerant completely due to exception
In the case of, the refrigerant inflow heat exchanger 31 of low temperature, therefore vacation is less than by the temperature of the refrigerant of temperature sensor detection
Fixed temperature.In this case, control unit 15 can be detected as producing exception in expansion valve 51c.And then control unit 15 is right
Solenoid valve 52 carries out closing control, interdicts the flowing of refrigerant.
As described above, by carrying out closing control to solenoid valve 52 only in expansion valve 51c exceptions, solenoid valve can be reduced
52 opening and closing number, so as to improve the service life of solenoid valve 52.
In addition, the temperature sensor detection expansion valve of the upstream side by being set to heat exchanger 31 has been illustrated here
The situation of the abnormality of 51c, however, it is not limited to this, can also according to from flow sensor, pressure sensor, be set to
The detection information of the temperature sensor of primary circuit 37 etc. detects the abnormality of expansion valve 51c.
In addition, as shown in figure 3, expansion valve 51a can be contained in operation of air conditioner indoor unit 302a, by expansion valve
51b and expansion valve 51c are contained in branch units 305, thus form air conditioning hot supply hybrid system 100.In addition, Fig. 3 is

It is bright.
The air conditioning hot supplies hybrid system 200 and the air conditioning hot supply hybrid system 100 involved by embodiment 1 is same
Implement to sample the refrigeration cycle operating of steam compression type, thus, it is possible to processing simultaneously in operation of air conditioner with being selected in indoor unit
Refrigeration operation or heating operation and the hot water supply of hot water supply unit operating.
In addition, in embodiment 2, illustrate a heat source unit be connected with two operation of air conditioner indoor units and
The situation of one hot water supply unit, however, it is not limited to this, can have number of units more than diagram respectively.
In the embodiment 1, the structure that solenoid valve 52 is equipped on to branch units 305 has been illustrated, but in embodiment party
In formula 2, make solenoid valve 52 and branch units 305 relatively independent set.
Specifically, solenoid valve 52 is not carried in branch units 305, but will be with 305 independently arranged electricity of branch units
Solenoid valve unit 306 is set between hot water supply unit 303 and branch units 305, and solenoid valve is carried in electromagnetic valve unit 306
52。
Electromagnetic valve unit 306 is equivalent to " Unit the 5th " of the utility model.
As described above, in air conditioning hot supplies hybrid system 200, make electromagnetic valve unit 306 only with branch units 305
It is vertical.Therefore, hybrid system 200 is supplied according to air conditioning hot, in addition to the air conditioning hot involved by embodiment 1 supplies compound system
Outside the effect that system 100 is played, additionally it is possible to minimize branch units 305, so as to improve the degree of freedom of installation.
