And control described electromagnetic valve to open and the closing of the second throttle part；
Receive refrigeration and heat water running instruction when, control cross valve by the exhaustor of described oil separator component
Connect with the first port of outdoor heat exchanger, the entrance of low-pressure tank is connected with described first stop valve, and control described electromagnetism
Valve cuts out and described second throttle part is opened.
In this embodiment, when heat pump is when heating water running, by controlling cross valve by oil separator component
Exhaustor is connected with the first stop valve, is connected the first port of outdoor heat exchanger with the entrance of low-pressure tank, and controls electromagnetic valve
Open and the second throttle part is closed so that coolant can be without indoor set directly by above-mentioned electromagnetic valve and through above-mentioned the
Enter outdoor heat exchanger after one throttle part throttling, after outdoor heat exchanger evaporation, return compressor.And in heat pump system
Cold and when heating water running, opened so that coolant can sequentially pass through outdoor heat exchanger, interior is changed by controlling above-mentioned electromagnetic valve
Hot device, is then back to compressor, on the premise of ensureing refrigeration, realizes the function of water heating.
In summary：
For the heat pump shown in Figure 10, when there being water heating demand, if it is in operation and oily compressor 101 is detected
The outlet temperature of the exhaustor 22 of separator assembly is higher than temperature Tr setting, then water circuit system can detect the water in water tank 109
Whether position S is less than default lowest water level S1, if S≤S1, opens water compensating valve 111 and supplements water level.Wherein, opening moisturizing
When valve 111 supplements water level, water pump 110 and flow control valve 113 can be closed, because after water compensating valve 111 is opened, hydraulic pressure pushes away enough
Water in dynamic pipeline enters water tank 109, and now, the aperture of water compensating valve 111 is according to the leaving water temperature T of outlet 330To set, to keep away
The aperture exempting from water compensating valve 111 larger leads to cooling medium liquefaction.
If S ＞ S1 is detected when just starting, open water pump 110 and flow control valve 113, now water compensating valve 111 closes
Close, the aperture of flow control valve 113 is according to the leaving water temperature T of outlet 330To set.When the temperature in water tank 109 is detected
When Tw reaches design temperature, then detect whether the water level S in water tank 109 is more than default peak level S2, if S >=S2,
Switch off the pump 110 and flow control valve 113, and determines that water heating completes, and now can send and heat the instruction that water energy need to be zero
To controller；And if S<S2, then switch off the pump 110 and flow control valve 113, and opens water compensating valve 111, water compensating valve 111
Aperture is according to the leaving water temperature T of outlet 330To adjust.No matter whenever, if detect water level S in water tank 109 >=
S2, then water compensating valve 111 will positive closing, prevent water level overflow.
In an embodiment of the present utility model, heat pump can have refrigeration mode, heating mode, water heating mould
Formula, freeze and heat aqueous mode, dehumidification mode and air supply pattern etc., only heating aqueous mode and refrigeration and heating aqueous mode
When, just determine there is the demand of water heating, and when the demand of water heating is only detected, water circulation system just can be run.Work as heat
Pumping system run refrigeration mode, heating mode, dehumidification mode with during air supply pattern as common heat pump, now water route
Circulation is closed.
Specifically, when heat pump runs and heats aqueous mode, off-premises station receives from remote control or line control machine
The water heating demand sending, electricity commutation on cross valve 102, electromagnetic valve 105 is opened, and the electric expansion valve of indoor set is (i.e. above-mentioned
The second throttle part) close, compressor 101 according to can need size determine running frequency.The high temperature discharged from compressor 101 is high
Pressure gaseous coolant enters oil separator component from air inlet pipe 21, realizes the separation of oil and coolant under the action of the centrifugal force, simultaneously high
Warm coolant carries out heat exchange with the recirculated water from water tank 109 side in cavity, and the coolant after Oil-gas Separation and cooling is from aerofluxuss
Pipe 22 out through the throttling action of cross valve 102, electromagnetic valve 105 and electric expansion valve 104 (i.e. above-mentioned first throttle part),
Return to compressor 101 and complete coolant through cross valve 102, low-pressure tank 106 again after evaporation endothermic amount in outdoor heat exchanger 103 and follow
Ring.And the lubricating oil in oil separator component then returns compressor 101 through oil return pipe 23, and water passage circulation system is according to above
Control logic run.
When heat pump runs refrigeration and heats aqueous mode, off-premises station receives and sends from remote control or line control machine
The refrigeration come and water heating demand, cross valve 102 is closed, and electromagnetic valve 105 cuts out, and electronic expansion valve of indoor unit is according to the actual requirements
Be adjusted, compressor 101 according to can need size determine running frequency.The high pressure gaseous coolant discharged from compressor 101
From air inlet pipe 21 enter oil separator component, under the action of the centrifugal force realize oil and coolant separation, simultaneously high temperature refrigerant with come
Recirculated water from water tank 109 side carries out heat exchange in cavity, and the high pressure middle temperature coolant after Oil-gas Separation and cooling is from exhaustor
22 out enter outdoor heat exchanger 103 condensation cooling through cross valve 102, then through electric expansion valve 104 from the second stop valve
107 get in machine, return to off-premises station from the first stop valve 108 indoors after evaporation endothermic in machine, then through cross valve 102,
Low-pressure tank 106 returns to compressor 101 and completes refrigerant circulation.And the lubricating oil in oil separator component then returns through oil return pipe 23
Compressor 101, and water passage circulation system runs according to control logic above.
Wherein, for the heat pump shown in Figure 10, due to being not provided with oil storage tank inside oil separator component, therefore in water
To guarantee during loop control that the outlet temperature of exhaustor 22 is not less than the saturation temperature of coolant, to avoid the occurrence of compressor liquid hammer
Problem.
Based on this, as shown in figure 11, oil separator component adopts the structure shown in Fig. 7, arranges oil storage in tank body 24
Tank 71, this structure makes the control of water circuit system not limited by the saturation temperature of gaseous coolant, and water heating is faster more energy efficient.
The control logic in water route is as described above, but need not be according to the leaving water temperature T of outlet 330Water compensating valve 111 and stream are set
The aperture of control valve 113, and under this configuration, flow control valve 113 can also be set in water route.
Additionally, for the heat pump shown in Figure 10 and Figure 11 it is also possible to the going out of exhaustor 22 in oil separator component
Arrange pressure transducer at mouthful to detect refrigerant pressure.
To sum up, this utility model provides a kind of new oil separator component, can be assembled with water- to-water heat exchanger assembly
Constitute new heat exchanger, this novel heat exchanger can be real under the premise of realization is normally oily and cold media gas are detached
The now heat exchange with water, increased the function of petroleum crude separator, and the feature of modularization assembling has higher motility, simultaneously
Also allow for safeguarding and remove incrustation scale.Based on the novel heat exchanger proposing, this utility model also proposed a kind of new Heat Pump
Hydrophone, realizes the function of water heating, decreases heat pump system on the premise of being increased without cross valve and bushing type water- to-water heat exchanger
