Abstract
The utility model discloses a supercharged air source heat pump water heater, wherein an injector used for supercharging the system is arranged in the system; the injector consists of a pressure-reducing section, a mixing chamber and a pressure-increasing section; a bypass with a flow control valve is arranged at the outlet of a compressor and connected with the inlet of the injector; an adapter is arranged at the throat part of the injector and connected with the outlet of an evaporator; the outlet of the injector is connected with the inlet of the compressor; and after a high-temperature high-pressure fluid as working fluid is guided from a bypass pipe to the injector, a low-pressure condensing agent is introduced from the evaporator, and then both the fluid and the condensing agent enter the pressure-increasing section to increase the pressure, thereby achieving the supercharging purpose. The supercharged air source heat pump water heater can effectively increase the intake pressure, reduce the exhaust temperature, improve the low-temperature performance of the heat pump and enlarge the application range of the air source heat pump.
Description
Technical field
The present invention relates to heat pump, particularly the air source heat pump technical field.
Background technology
Just as we all know, traditional air source hot pump water heater mainly is made up of parts such as compressor, condenser, expansion valve and evaporimeters.At first, enter condenser after the compressed machine compression of condensing agent, emit heat and make heating or domestic hot-water's usefulness, and after the heat release of condensing agent own, then enter the expansion valve step-down, and then enter evaporimeter, here it absorbs energy from air and becomes the low pressure condensing gas, is sucked by compressor again at last and finishes a circulation.
Air source heat pump does not produce pollution owing to easy to use, and energy-saving effect is obvious, is subjected to paying attention to widely.
Yet, traditional air source hot pump water heater, it is not suitable for using under low temperature environment.This is because under low temperature environment, and evaporating temperature reduces, and evaporating pressure also reduces, and is certain as condensing pressure, and then pressure ratio increases, and increased exhaust temperatures has a strong impact on the generation of compressor life-span; Simultaneously, along with the reduction of evaporating pressure, heating capacity is reduced, Energy Efficiency Ratio also reduces.
For solving the operation problem of heat pump under low temperature environment, what have has set up auxiliary thermal source on the basis of original heat pump, as auxiliary thermal sources such as fire coal, fuel oil, combustion gas, to remedy the heat supply deficiency of heat pump under low temperature environment.But set up auxiliary thermal source and be subjected to many-sided restrictions such as architectural environment, safety, performance difficulty.The employing hydrojet mode that has, in the hope of the reduction delivery temperature, but it is very big to the economic influence of circulation; The compression of employing secondary, though can reduce pressure ratio, the also corresponding increase of cost investment, to middle-size and small-size, particularly the low profile thermal pump water heater also is unfavorable.
Summary of the invention
At the deficiencies in the prior art, the present invention discloses a kind of pressurized air source heat pump water heater, this system architecture is simple, can effectively improve the suction pressure of heat pump at low temperature environment lower compression machine, reduce pressure ratio, reduce the delivery temperature of compressor, thereby widened the scope of application of air source heat pump greatly.
The present invention is in the circulation of conventional heat pump water heater, set up a bypass of drawing from compressor outlet and the pressure charging system of an injector, injector partly is made up of decompression section, mixing chamber and diffuser three, shunt valve links to each other with the import of injector, the throat of injector has an interface to link to each other with the outlet of evaporimeter, and the outlet of injector links to each other with the suction line of compressor.The HTHP condensing gas of drawing from bypass, working fluid as playpipe enters injector, after the decompression section, reach minimum pressure in throat, the low pressure condensing gas that injection comes from evaporimeter, working fluid and driving fluid enter diffuser after mixing chamber mixes then, carry out reduction of speed and boost, bring up to maximum, reach the purpose that compressor sucks supercharging in the injector outlet pressure.
Description of drawings
Figure of description is a pressurized air source heat pump water heater flow chart of the present invention.
The specific embodiment
A is a compressor among the figure, and B is a condenser, and C is an expansion valve, and D is an evaporimeter, and E is an injector.
Among the figure 1 ' 23411 ' and be pressurized air source heat pump water heater circular chart of the present invention, the 12341st, conventional air source heat pump water heater circular chart.
Referring to accompanying drawing, at first state 1 ' the compressed machine of condensing agent be compressed to state 2, enter the condenser heat release to state 3, be depressurized to state 4 through expansion valve, then enter evaporimeter and absorb heat to state 1, then, state 2 condensing agents that come out from the compressor outlet bypass, enter injector as working fluid and be expanded to the minimum pressure state 1 that throat locates in the decompression section, and at the condensing agent of throat's place's injection from the state 1 of evaporator outlet.Two fluid streams enter diffuser after the injector mixing chamber mixes, reduction of speed boosts, and boosts to state 1 in the exit, reaches the purpose of supercharging, and the condensing agent after this supercharging is sucked by compressor and finishes a circulation.
In order to regulate the injector outlet pressure, from the shunt valve of compressor outlet, be provided with a flow control valve (not drawing among the figure), regulate the size of flow, can control the degree of supercharging.
Pressurized air source heat pump water heater of the present invention, its suction pressure can obviously improve, and it helps using in low temperature environment, has widened the scope of application of air source water heater.
