1be connected, form heat pump cycle path.
Be connected with magnetic valve B13 between the Heating medium B of high temperature storage 4 and heating agent outlet B, short circuit can be formed to high temperature storage 4.Economizer 15 is other is provided with a branch road, and branch road is provided with liquid-filling valve 14, can form short circuit to economizer 15, makes cold-producing medium directly get back to compressor 1 Heating medium A
2, opening liquid-filling valve 14 can inject liquid refrigerant, cools to gaseous refrigerant.Pipeline E is provided with a tonifying Qi expansion valve 16, cold-producing medium is sent back to economizer 15, goes back to the second vapor injection chamber of compressor 1 after absorbing heat vaporization.Pipeline F is provided with heating power expansion valve 17 parallel with one another and relief arrangement, and relief arrangement comprises capillary 22, off-load magnetic valve 21 and the check valve 20 of mutually connecting.Open off-load magnetic valve 21 and can carry out off-load, reduce exhaust lateral pressure.
During work, this device is divided into two circulatory systems to carry out work.In heat pump circulating system, the high-temperature high-pressure gas refrigerant that compressor 1 is discharged is by entering the strengthening turbulent flow coil pipe 12 in high temperature storage 4 after cross valve 2, to the sensible heat of high temperature storage 4 refrigerant release, thus in high temperature storage 4, produce the high-temperature hot water of 75 degree, spiral heat exchanger 11 during cold-producing medium after release sensible heat arrives in warm volume device 5 discharges latent heat, coolant-temperature gage in middle temperature volume device 5 is produced dynamic design temperature, therefrom warm volume device 5 medium temperature and medium pressure liquid refrigerant arrival economizer 15 out carried out cold, cross cold after liquid refrigerant be divided into two-way, one tunnel arrives main heating power expansion valve 17 and carries out reducing pressure by regulating flow, another road is to tonifying Qi expansion valve 16.Cold-producing medium through heating power expansion valve 17 arrives finned heat exchanger 19, after absorbing heat, becomes gaseous refrigerant from air, then by returning compressor 1 after cross valve 2 to vapour liquid separator 3.And get back to economizer 15 by the cold-producing medium of tonifying Qi expansion valve 16, go back to the second vapor injection chamber of compressor 1 after absorbing heat vaporization.When high pressure reaches 2.8MPa, off-load magnetic valve 21 is opened, and carries out off-load, reduces exhaust lateral pressure, protection compressor 1.When high pressure drops to 2.6MPa, close off-load magnetic valve 21.When delivery temperature is more than 110 degree, liquid-filling valve 14 is opened, and carries out fluid injection to the gas refrigerant going out finned heat exchanger 19, thus reduces delivery temperature, when delivery temperature is lower than 100 degree, closes liquid-filling valve 14.When the water temperature in high temperature storage 4 reaches 80 degree, open the magnetic valve 13 that high temperature storage 4 is other, unit does not need to heat high temperature storage 4, when temperature is lower than 75 degree, then shut electromagnetic valve 13.
Heat-flash and energy-conservation two kinds of mode of operations are had in the heating agent circulatory system.Initial heating or indoor temperature change generated in case too large time, in order to be rapidly heated, adopt heat-flash mode of operation; Now enable the hot water in high temperature storage 4, regulated by Three-way Thermostatic Valve 10, the water in high temperature storage 4 and middle temperature volume device 5 supplies radiator by Three-way Thermostatic Valve 12, Three-way Thermostatic Valve 12 control of export temperature 65 degree simultaneously.Water pump A6 and water pump B7 opens simultaneously, and the water temperature now owing to supplying radiator 9 is high, flow large, and the radiating effect of heating installation is multiplied, and so just promptly indoor temperature can be warmed up to design temperature.When indoor temperature is close to design temperature, adopt saving operation mode; According to the difference of indoor temperature and design temperature, in dynamic conditioning, the water temperature of warm volume device 5 and Three-way Thermostatic Valve 10 export C temperature, realize the dynamic conditioning of heating temperature.
When source pump is operated in heat-flash pattern, when water temperature in middle temperature volume device 5 reaches 55 degree, and the water temperature in high temperature storage 4 is when reaching 75 degree, source pump is in stopped status, when water temperature in central warm volume device 5 reduces by 2 degree, source pump start heats, if the temperature now in high temperature storage 4 is lower than 75 degree, then the magnetic valve 13 on high temperature storage 4 limit keeps closed condition, now source pump also heats high temperature storage 4, when the temperature in high temperature storage 4 reaches 80 degree, magnetic valve 13 is opened, high temperature storage 4 is not heated, water in centering temperature volume device 5 heats.If when the water temperature in middle temperature volume device 5 reaches 55 degree, water temperature now in high temperature volume device 4 is lower than 70 degree, then start high temperature storage 4 to heat separately, open the magnetic valve 8 in radiator 9 bypass, open two water pumps and source pump, Inner eycle heating is carried out to high temperature storage 4, when water temperature reaches 75 degree, closes source pump.
