Description
Technical field
The present invention relates to the technical field of water heater, is a kind of water habits different according to user specifically, the heat time of automatic decision setting hot water, thus reduces the operation method of the Teat pump boiler of hot water waste in water butt.
Background technology
Teat pump boiler utilizes inverse Carnot's principle exactly, by medium, heat is delivered to the equipment the water of high temperature from cryogenic object.Heat pump assembly, can make medium (refrigerant) phase transformation, become lower than low-temperature heat source, thus spontaneous absorption heat of low-temperature heat source; Get back to the medium after compressor, be compressed into again high temperature (also higher than the water of high temperature) gases at high pressure, thus spontaneous heat release is to high temperature heat source; Realize from by the device of the transfer of heat of low-temperature heat source to the water of high temperature.Because electricity is not participate in heating directly, so required electricity is not a lot, and the utilization rate of electric energy is higher.
Current domestic and international market Teat pump boiler mainly contains two kinds: one is that evaporimeter absorbs heat from air, progressively raises the water temperature in condenser come the equipment of water heating, be called air source hot pump water heater by conversion; Another kind is that evaporimeter absorbs heat from water, raises the water temperature in condenser come the equipment of water heating, be called water source heat pump water heater by conversion.
Existing Teat pump boiler, comprising: shell, and form the outward appearance of water heater, and hold all parts of water heater, enclosure is divided into host machine part and bucket part; Evaporimeter, is arranged on the host machine part of Teat pump boiler, with air generation heat exchange; Fan, is arranged on host machine part, will guide for periods of heating in air intake to shell; Fan electromotor, for fan provides power, drive fan continues to rotate; Compressor, by the liquid refrigerants of gaseous coolant boil down to HTHP and order about refrigerant flowing; Water butt, is arranged on above-mentioned bucket part, it draws cold water inlet and hot water outlet, holds and store water; Coil pipe, is arranged in water butt, and one end is connected with the refrigerant exit of compressor, and the other end is connected with evaporimeter, and guiding refrigerant flows in coils and carries out heat exchange with the cold water in water butt.Compressor and motor rotation when accessing power supply, high temperature refrigerant after compressor compression flows through coil pipe, in storage tank, the coil pipe of high temperature and cold water carry out exchange heat, water temperature in water butt is raised, refrigerant expansion valve, get back to compressor after evaporimeter thus complete circulation, along with the running of fan electromotor, fan starts to rotate, room air enters into enclosure by the air inlet that shell host machine part is arranged, and carry out heat exchange with evaporimeter, the temperature of refrigerant is raised, thus by the transfer of heat in room air in refrigerant, then air flows back to indoor by exhaust outlet again.Then refrigerant is inhaled into compressor inside again, thus starts refrigerant circulation next time.
