Description
Technical field
The utility model relates to a kind of air source hot pump water heater.
Background technology
The US6233958 patent documentation discloses a kind of Teat pump boiler, this Teat pump boiler comprises a refrigerating circuit of being made up of compressor 136, heat exchanger 162, expansion valve 142, evaporimeter 146 order connections, the condensation heat of this refrigerating circuit is by inserting the water heating in the 162 pairs of boilers 114 of pipe heat exchanger in the boiler, referring to Fig. 1.This Teat pump boiler is subjected to extensive concern in recent years because energy consumption is lower.But the cold-producing medium in this Teat pump boiler is to circulate in the longer pipe road, therefore exists refrigerant tubing longer, and cold-producing medium leaks easily, the more high defective of cost.
Summary of the invention
The purpose of this utility model is to propose a kind of integrated thermal pump water heater, adopts a kind of water heat exchanger, and water heat exchanger and refrigerant system are integrated, and by water pipe hot water is imported boiler again and stores, to overcome the deficiencies in the prior art.
A kind of integrated thermal pump water heater of the present utility model, comprise refrigerant circulation loop 10, this refrigerant circulation loop is communicated with by compressor 1, water heat exchanger 3, throttle mechanism 4 and air heat exchanger 5 orders and forms, it is characterized in that: also have one and add hot water circulation loop 20, this water-flow circuit is communicated with in order by water pump 21, water heat exchanger 3 and boiler 22 and forms, described water heat exchanger 3 and refrigerant circulation loop 10 integrated being assembled in the housing 6.
For device 5 frostings that avoid evaporating, in refrigerant circulation loop, between compressor 1 and water heat exchanger 3, also can be provided with a cross valve 2, a path of this cross valve is with water heat exchanger 3 short circuits, can under controlled situation, make the refrigerant gas of HTHP directly not flow to evaporimeter 5, thereby realize automatic defrosting by water heat exchanger 3.
Advantage of the present utility model is: (1) is because refrigerant circulation loop 10 and water heat exchanger 3 integrated being assembled in the housing 6, therefore the circulating line of cold-producing medium is very short, the substitute is and add hot water circulation loop 20, but because the relatively good processing of leakage of water-flow circuit, and it is less to the influence of environment, cost is also low, so its effect is more outstanding; (2) because the hot water temperature in the water-flow circuit is more much lower than the refrigerant temperature in the cold-producing medium circulation, therefore heat loss is less in transmission course, simultaneously because adopted plate type heat exchanger, has therefore improved the thermal efficiency, this device can obtain about 70 ℃ hot water without electrical auxiliary heater; (3) be the control device at center owing to having adopted, make the operation of this device more reasonable, control more convenient with CPU.
Description of drawings
Now the utility model is described in further detail in conjunction with an embodiment and accompanying drawing thereof.
Fig. 1 is the schematic diagram of existing single loop Teat pump boiler;
Fig. 2 is the structural representation of Teat pump boiler of the present utility model;
Fig. 3 is a control device schematic diagram of the present utility model.
Embodiment
Structure of the present utility model, as Fig. 2, comprise refrigerant circulation loop 10 and a hot water circulation loop 20, this refrigerant circulation loop is by compressor 1, cross valve 2, water heat exchanger 3, throttle mechanism 4 and air heat exchanger 5, be communicated with to compressor 1 order and form again, hot water circulation loop 20 is by water heat exchanger 3, water pump 21, and boiler 22, arrive water heat exchanger 3 again and be communicated with composition in order, described water heat exchanger 3 and refrigerant circulation loop 10 integrated being assembled in the housing 6, a path B of described cross valve 2 is with water heat exchanger 3 short circuits.
Be provided with a cross valve 2 between compressor 1 and water heat exchanger 3, a path A of this cross valve 2 connects compressor 1 and water heat exchanger 3, is connected with throttle mechanism 4 then; The described water heat exchanger 3 of another path B short circuit, promptly compressor 1 directly is connected with throttle mechanism 4.Because this cross valve 2 can make the cold-producing medium water heat exchanger 3 of not flowing through directly flow to throttle mechanism 4 and evaporimeter 5 under controlled situation, thereby the refrigerant gas that can utilize HTHP is to evaporimeter 5 automatic defrostings.
Described water heat exchanger adopts plate type heat exchanger.Plate type heat exchanger is a kind of heat exchanger of superior performance, adopts thin heat exchange plate soldering to form, and has the high coefficient of heat transfer and little liquid holdup, thus compact conformation, durable, in light weight, performance is good, operating cost is low.
The order that described hot water circulation loop 20 also can be by water heat exchanger 3, boiler 22 and water pump 21, arrive water heat exchanger 3 again is communicated with to be formed.
In the Teat pump boiler, also be provided with CPU is the control device at center, as Fig. 3, this device is except that CPU, at least also comprise the temperature sensor 31, the pressure sensor 32 that detects compressor 1 pressure at expulsion that detect compressor 1 delivery temperature, be located at temperature sensor 33 and pressure sensor 34 in the water tank 22, the input block 40 of section heat time heating time, heating-up temperature can be set, data display unit 60 and control instruction output unit 50.
When the detecting temperature and surpass detecting pressure and surpassing setting value of setting value or compressor discharge pressure sensor 32 of compressor exhaust temperature sensor 31, control device has the start and stop of control compressor, the function of protection compressor.
When the water temperature sensor 33 of boiler 22 detected temperature above setting value, control device had the start and stop of control compressor, the characteristics of energy savings.
