Heat exchange is formed between a water side loop and a refrigerating agent side loop through a plate type heat exchanger; the water side loop comprises a water side room heat radiator, a water side heat exchanger, a water pump and a heat exchanger, which are connected in series; the refrigerating agent side loop comprises an evaporator, a compressor, an air cooler and an expansion valve, which are connected in series; the water side heat exchanger is connected behind the water side room heat radiator in series; and the water side heat exchanger is arranged at a dead wind part beside the evaporator in the refrigerating agent side loop. Compared with the prior art, the compression ratio of the compressor can be reduced, the system power consumption is reduced and the defrosting time of the system can be greatly reduced.
Description
Technical field
The utility model relates to CO
2Heat pump water heater system especially relates to a kind of carbon dioxide heat pump water heater water side loop structure.
Background technology
In recent years, along with environmental protection, ideas of energy-saving are rooted in the hearts of the people, the requirement of using air-conditioning, Teat pump boiler is tended towards superiority, they had the more and more higher life-span except needs, also needed as far as possible it to reduce energy consumption.Studies show that CO
2Teat pump boiler can save energy 75% with respect to common electric heater, and energy-saving potential is huge.Teat pump boiler can also use as floor heating and the heating of hot water spit of fland except the domestic hot-water directly is provided for family.Because CO
2Working medium heating operating mode heat exchanger inflow temperature raises, advance/temperature difference of outlet water reduces, so water side heat exchange amount reduces, system heats COP and descends.
The computational methods of water side heat exchange amount are:

2The heating operating mode is compared with heat pump working condition, and water effluent amount slightly increases, but the reduction of the heat exchanger Inlet and outlet water temperature difference, generally speaking, water side heat exchange amount will reduce.If system power dissipation is constant, CO
2Heating the relative heat pump working condition of COP and will descend to some extent during heat pump water heater system operation heating operating mode.
The utility model content
The purpose of this utility model is exactly to provide a kind of compresses machine pressure ratio for the defective that overcomes above-mentioned prior art existence, reduces system power dissipation, and the carbon dioxide heat pump water heater water side loop structure that system's defrosting number of times is reduced greatly.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of carbon dioxide heat pump water heater water side loop structure forms heat exchange between this water side loop and the refrigerant side loop, wherein,
The water side loop comprises water side room radiator, water-side heat, water pump and the heat exchanger of series connection;
The refrigerant side loop comprises evaporimeter, compressor, air cooler and the expansion valve of series connection;
Described water-side heat is connected on the back of water side room radiator, this water-side heat is arranged on the other against the wind place of evaporimeter in the refrigerant side loop, so that the air that evaporator fan sucks is first through the water-side heat heating, again with the heat exchange of refrigerant side evaporimeter.
Described heat exchanger and air cooler consist of plate type heat exchanger, and wherein heat exchanger is connected in the water side loop through pipeline, and air cooler is connected in the refrigerant side loop through pipeline.
Described water side loop also is provided with pipeline and the valve that makes things convenient for switchover operation heat pump working condition or heating operating mode.
Compared with prior art, the utility model namely keeps the room radiator to import and export under the condition of water temperature not affecting the heating comfort, the water of abdicating the room radiator continues heat release, utilize this part heat heating and cooling agent side evaporimeter environment temperature, improve cold-producing medium evaporating temperature/pressure, compresses machine pressure ratio reduces system power dissipation, heats COP during finally raising system operation heating operating mode.Another advantage is that the water-side heat liberated heat has also improved refrigerant side evaporator inlet temperature simultaneously, so that system's defrosting number of times reduces greatly.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1 is that water side room radiator, 2 is that heat exchanger, 3 is that air cooler, 4 is that plate type heat exchanger, 5 is that compressor, 6 is that water pump, 7 is that expansion valve, 8 is that evaporimeter, 9 is water-side heat.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of carbon dioxide heat pump water heater water side loop structure, its structure as shown in Figure 1, form heat exchange between this water side loop and the refrigerant side loop, wherein, the water side loop comprises water side room radiator 1, heat exchanger 2, water pump 6 and the water-side heat 9 of series connection, and the refrigerant side loop comprises evaporimeter 8, compressor 5, air cooler 3 and the expansion valve 7 of series connection.At water side room radiator 1 rear series connection one water-side heat 9, this water-side heat 9 is arranged on the evaporimeter 8 other against the wind places in the refrigerant side loop, so that the air that evaporator fan sucks is first through water-side heat 9 heating, again with evaporimeter 8 heat exchange.Heat exchanger 2 and air cooler 3 consist of plate type heat exchanger 4, and wherein heat exchanger 2 is connected in the water side loop through pipeline, and air cooler 3 is connected in the refrigerant side loop through pipeline.Some pipelines and valve are set, the pipeline of flowing through of water when making things convenient for this carbon dioxide heat pump water heater switchover operation heat pump working condition or heating operating mode in the loop.
The utility model is the convenient CO that switches
2Teat pump boiler water side loop structure, when heating COP when guaranteeing its operating heat pump operating mode, system power dissipation when reducing its operation heating operating mode improves the heating operating mode and heats COP, improves CO
2The whole competitiveness of heating in heating market.
