Abstract
The invention discloses a pressurized air source heat pump water heater, and an ejector used for leading a system to be pressurized is arranged inside the system. The ejector consists of a decompression section, a mixing chamber and a pressure-increasing section; an outlet of a compressor is provided with a bypass provided with a flow rate regulating valve, and the bypass is connected with an inlet of the ejector. The throat part of the ejector is provided with an interface which is connected with an outlet of an evaporator; an outlet of the ejector is connected with an inlet of the compressor, high temperature and high pressure fluid led out from a bypass pipe is taken as working fluid, after entering the ejector, the working fluid injects low-pressure condensed gas from the evaporator, and then entering into the diffusion section together, so that the pressure is increased, and the aim of pressurization is achieved. The pressurized air source heat pump water heater can effectively increase the intake pressure, reduces the exhaust temperature, improves the low temperature performance of a heat pump, and expands the application scope 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 sets up a bypass and an injector of drawing from compressor outlet in the circulation of conventional heat pump water heater, injector partly is made up of decompression section, mixing chamber and diffuser three, and shunt valve links to each other with the import of injector.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, boost in the exit state 1 ', reach the purpose of supercharging, 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.
