Abstract
The invention provides an instant heating heat pump water heater, which mainly comprises a high-power compressor, an evaporator, a pressure reducing valve, a frequency converter, a heat exchanger, an induction element, a controller and a water inlet and outlet pipeline, wherein the compressor is connected with the frequency converter, the water heater does not need a hot water storage tank, a plurality of strands of refrigerants and cold water pipelines are mutually wound in the heat exchanger, the induction element can induce the opening and closing of a water outlet end, the heat pump can be automatically started when the water outlet end discharges water, the high-temperature and high-pressure refrigerants heat cold water through the heat exchanger, the controller can set the temperature and adjust the power of the compressor through the frequency converter so as to control the temperature of the discharged water, the instant heating water heater has the obvious effects that the high-power compressor is adopted for rapid heating by changing the power of the compressor, the instant heating can be realized, the large water storage tank of the conventional heat pump water heater, not only is convenient, but also prolongs the service life.
Description
Technical field
The present invention relates to a kind of water heater, especially a kind of instant-heating hot pump water heater.
Background technology
Teat pump boiler utilizes contrary Carnot's principle exactly, heat is delivered to a kind of water heater of high temperature from low temperature.Heat pump is a kind of device, it can be from surrounding environment draw heat, and by working medium the heated object of heat transferred (object that temperature is higher than surrounding environment).Its work principle is the same with refrigerating plant, only uses conversely.It utilizes the heat-absorbing medium (refrigerant) in the equipment to gather heat energy from air or natural environment, and makes the rapid temperature raising of cold water by heat exchanger, gives off cold air simultaneously.Avoided traditional solar product in inoperable defective of rainy weather, night, as long as ambient temperature just can operate as normal more than the 1-15 degree, so can be more efficient, energy-conservation, can not account for open-air space simultaneously, installs simple and direct, use is flexible.The main device of a heat pump is made up of evaporimeter, condenser, compressor, expansion valve.Because electricity is not to participate in heating directly so required electric weight is not a lot.The heat utilization efficiency of electric energy can reach 300%.
At present, the water heater kind on the market is a lot, and present electric heater mostly is Instant heating type, and Teat pump boiler mostly is storage-type greatly, and it is big to take up room, and makes its use restricted greatly, and non-Instant heating type heating makes it consume most electric energy and is used for heat accumulation, needs to improve.
Summary of the invention
At the problems referred to above, the invention provides a kind of instant-heating hot pump water heater.
A kind of instant-heating hot pump water heater, mainly by high-power compressor, evaporimeter, pressure-reducing valve, frequency converter, heat exchanger, sensing element, controller and inlet and outlet pipe lines are formed, it is characterized in that compressor is connected with frequency converter, water heater does not need the hot water storage tank, there are multiply refrigerant and cold water pipes to twine mutually in the heat exchanger, sensing element can induce water end (W.E.) and open and close, automatically start heat pump during the water side water outlet, the HTHP refrigerant is through heat exchanger heating cold water, controller can design temperature and is adjusted the power of compressor by frequency converter, with the control leaving water temperature.
Remarkable result of the present invention is by changing the power of compressor, adopt high-power compressor Fast Heating, can in time heat, need not the large-scale water tank of conventional Teat pump boiler, and do not need long-time insulation and the waste electric weight, the employing of frequency-changeable compressor makes temperature also can carry out random control, and is not only convenient, also prolonged service life.
Description of drawings
Accompanying drawing is the instant-heating hot pump water heater schematic diagram
Wherein: 1, cooling water inlet; 2, heat exchanger; 3, evaporimeter; 4, high-power compressor; 5, pressure-reducing valve; 6, hot water outlet; 7, controller; 8, sensing element; 9, frequency converter.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing: high-power compressor 4 is connected with frequency converter 9, water heater does not need the hot water storage tank, sensing element 8 can induce water end (W.E.) and open and close, automatically start heat pump during hot water outlet 6 water outlets, cold water enters heat exchanger 2 from cooling water inlet 1, be converted into the gas of high-temperature low-pressure behind the liquid refrigerants process evaporimeter 3 absorbing environmental heats of low-temp low-pressure, through compressor 4 boil down to high temperature and high pressure gas, enter heat exchanger 2 heating cold water then, the liquid coolant of last cryogenic high pressure enters pressure-reducing valve 5 and enters evaporimeter 3 and absorbs heat once more, controller 7 can design temperature and the temperature adjustment signal is passed to frequency converter 9, frequency converter 9 is adjusted the power of compressor 4 again, with the control leaving water temperature.
The invention has the beneficial effects as follows by changing the power of compressor, adopt the high-power compressor Fast Heating, Can in time heat, need not the large-scale water tank of conventional Teat pump boiler, and not need long-time insulation and wave Take electric weight, the employing of frequency-changeable compressor so that temperature also can carry out Random control, not only convenient, also prolonged service life, can save 25% power consumption.
