Description
Technical field
The present invention relates to the heat energy technical field, be specially a kind of heat pump water heater of dehumidification air conditioner.
Background technology
Along with the fast development of industry, day being becoming tight of the energy in the world wide, energy crisis becomes that the whole mankind must face and one of the key subjects that will solve.Adopting high efficiency energy-saving domestic electrical equipment is as one of six big emphasis energy-saving field---the effective way of commerce and domestic energy-saving.
Water heater is high-grade energies such as one of more household appliances of family's consumes energy, the main consumed power of electric heater and gas heater, natural gas and coal gas.Though the development of solar water heater has obtained great popularization, limited by weather and mounting condition.Teat pump boiler becomes main developing direction efficiently at present.
High humidity environment is prone to cause bacteria breed, brings out breathing problem, rheumatism, causes like the mouldy loss that waits property of making moist of clothes leather; Cause the human-body radiating difficulty summer, increase the possibility of heatstroke; Quicken the conduction of heat winter, makes the people doubly feel cold.Therefore, the dry and comfortable health in maintenance room becomes people's pursuit high-quality an aim in life.
Air-conditioner is one of present principal home's electrical appliance, and main consumed power makes temperature, relative humidity, pure and fresh degree, the cleanliness factor of room air satisfy the requirement of people to environmental degree of comfort.Along with the raising of resident living level, the application of room air conditioner is more and more wider.
At present, Teat pump boiler, dehumidifier and air-conditioner manufacturing technology are very ripe, but have a style of one's own, and are respectively applied for domestic hot water's supply, the humidity control of indoor environment and the control of indoor environment temperature.Wherein the Teat pump boiler technology has various ways such as wind source heat pump, solar heat pump and earth source heat pump.Dehumidifier has technology such as freeze drying, rotary wheel dehumidifying, liquid dehumidifying, film dehumidifying.Room air conditioner has the single-cooling type air-conditioning, refrigerating and heating type air-conditioning, three kinds of forms of electric assistant heating.
Teat pump boiler, dehumidifier and air-conditioner technology have synthetic to a certain extent.Like the patent No. be: 99228716.2; Patent name is: the Chinese utility model patent of multi-functional air conditioner refrigerating and heating combined equipment has disclosed a kind of multi-functional air conditioner refrigerating and heating combined equipment; Mainly form, comprise indoor and outdoor heat exchanger, compressor, reversal valve, heat-storing material case, water tank, subcooler and eddy flow flow control valve by a heat pump hot-water system and a heat pump type air conditioning system.Functions such as there is refrigeration in system, heats, Teat pump boiler, accumulation of heat.But the operation of the independent humidity control in this technical scheme only is to be realized by two condenser parallel connections; The refrigerant flow control difficulty can not realize the heat reasonable distribution, but can't realize temperature adjusting and dehumidifying; There is not effectively to solve the humidity control problem in room, relative humidity and temperature in can not the control room.
