Description
Technical field
The utility model relates to a kind of water heater, is specifically related to a kind of air source hot pump water heater.
Background technology
Water heater generally is divided into the fuel-firing gas-firing water heater at present, the electrical heating water heater, solar water heater, air source hot pump water heaters etc. are several, the fuel-firing gas-firing water heater is by the combustion fluid gasification, natural gas, kerosene, mineral such as alcohol or organic-fuel add a kind of water heater of hot water, thereby such water heater is subjected to the influence of the factors such as fluctuation of the burning degree of fuel and hydraulic pressure to cause fluctuating temperature bigger easily, and under the situation of oxygen supply deficiency, be easy to generate toxic gases such as carbon monoxide, may cause poisoning to take place when having very big injury serious to human body, the more important thing is needs to consume a large amount of a large amount of non-renewable resources of needs consumption, and use cost is higher, also bigger to ambient influnence.The electrical heating water heater is a kind of by consuming the water heater that high-grade electric energy adds hot water, and the water heater of the type uses more convenient, but lower to the service efficiency of electric energy, and the potential safety hazard of electric shock is arranged easily.Solar water heater is that a kind of vacuum tube that utilizes is collected the water heater that solar energy adds hot water, the water heater of the type, environmentally friendly and operating cost is low, but it is bigger that the water heater of the type is affected by weather conditions, the weather little at intensity of sunshines such as cloudy day, rainy days just is difficult to normal the use, thereby general solar water heater all has auxiliary electric heater unit, and solar water heater exists the defective same with the electrical heating water heater like this.
Air source hot pump water heater is that the contrary Carnot cycle principle of a kind of utilization is from the natural environment draw heat, and consume the water heater that a spot of electric energy raises its temperature energy transmission feedwater, air source hot pump water heater claims Teat pump boiler again, different with other power consumption water heater is, the electric energy of air source hot pump water heater consumption is intended for power and the service efficiency height that transmits energy, and the heat that hot water obtains is the heat sum that Teat pump boiler heat that obtains from environment and the electric energy that is consumed transform.The water heater of the type obtains a large amount of heat energy by consuming a spot of electric energy from natural environment, energy-saving efficiency is more than 4 times of electric heater, also more energy-conservation than solar water heater, thereby operating cost is low, and, not environmentally friendly to any harmful substance of environmental emission, realized electricity separation simultaneously, thereby avoid the generation of electric shock accidents, use safer.
Just because above-mentioned advantage air source hot pump water heater more and more is subjected to people's welcome, the field of using also more and more widely, generally include at least one by compressor, solenoid operated four-way valve, heat exchanger, throttling arrangement, evaporimeter along heat pump refrigerating loop that the cold-producing medium circulating direction is linked in sequence and forms, heat exchanger is arranged in the main water box, the water that is used for heating water tank, usually be provided with water inlet pipe and outlet pipe on the main water box, evaporimeter absorbs heat from atmosphere, heat exchanger heat release in the water tank is to heating from the water that water inlet pipe supplies in the water tank by circulating pump.At present, the compressor in the refrigerant loop is invariable frequency compressor, that is to say that compressor rotary speed is constant substantially, adjusts power output to drive, to stop compressor, thereby has following defective:
1. can not adapt under the wide loading condiction and move, because fixed air source water heater frequently is the unlatching of controlling compressor by the coolant-temperature gage difference in Inlet and outlet water temperature difference or the water tank, under the little situation of extraneous water requirement, be easy to cause the high frequent start and stop, the energy consumption of system is increased, and influence the service life of compressor.Though decide the compressor continuous operation of frequency under the big situation of extraneous water requirement, because the capacity limit of compressor can not realize the quick rising of water temperature;
2. can not realize stable operation in the wide temperature range, under the lower situation of environment temperature, fixed Teat pump boiler frequently normally starts difficulty, and cause excessive discharge temperature easily and shut down, under the environment temperature condition with higher, fixed Teat pump boiler frequently causes delivery temperature and pressure at expulsion superelevation easily and shuts down;
3. common invariable frequency compressor adopts asynchronous induction motor, have iron loss, so transformation efficiency is lower, and the starting current of deciding the frequency compression machine simultaneously is bigger, and is very big to the impact of electrical network, and can influence the normal use of other electrical equipment that moving;
4. can not under the low condition of environment temperature, move, cold-producing medium will absorb itself temperature of heat from surrounding air just must be lower than environment temperature, therefore environment temperature is low more, the evaporating temperature of cold-producing medium also just needs lower, corresponding evaporating pressure is also just low more, although the constancy of volume of the cold-producing medium that invariable frequency compressor is sucked in operation process, but the steam pressure of the cold-producing medium that is sucked is low, therefore the quality with the cold-producing medium that is comprised in the isometric(al) reduces, the mass flow that is the cold-producing medium of compressor reduces, and the heating capacity of Teat pump boiler is directly proportional with the mass flow of cold-producing medium.Studies show that when environment temperature-20 ℃, heating capacity can only reach about the 20%-30% of declared working condition, and because the work temperature difference constantly enlarges, the efficient of Teat pump boiler is also more and more lower, and so not only heating capacity can not satisfy customer requirements, and has lost its superiority efficiently.
