Background technology

Heat pump techniques is the novel energy technology that the whole world receives much attention in recent years, its basic principle is based on contrary Carnot cycle, the employing electric energy drives, draw heat from low-temperature heat source, and it is transferred to high temperature heat source for use, be transferred to heat in the high temperature heat source not only greater than the energy that is consumed, and greater than the energy that from low-temperature heat source, absorbs, under standard condition, the energy of a unit of system consumption, from low-temperature heat source, extract the energy of two units, lump together the energy of three units of output.

Heat pump mainly partly constitutes by four, is respectively compressor, radiator coil tube (being commonly called as condenser), expansion valve, heat absorption coil pipe (being commonly called as evaporimeter).The same with refrigerator, heat pump also is to utilize the cold-producing medium in the driven compressor pipeline to circulate, continuous evaporative condenser, after heating by cold-producing medium temperature difference heat absorption and compressor compresses, extraneous heat is gathered on the heat(ing) coil on the heat pump main frame endlessly, through high-tech Heat Conduction Material the water temperature in the water receiver is risen rapidly again.

At present, this heat pump is mainly used in industrial heat supply water or luxurious hotel's heat supply water, and the system that is used for industrial heat supply water or luxurious hotel usefulness heat supply water is owing to complex structure, and costing an arm and a leg is not suitable for sub-district central heating water.

Summary of the invention

The purpose of this utility model is to overcome the problems referred to above, provides a kind of simple in structure, with low cost, sub-district hot water supply system of being suitable for popularization to society.

The technical solution of the utility model is: design a kind of sub-district hot water supply system, comprise that heat pump, attemperater, total water valve and at least one cover comprise the house lead in device, the water inlet water receiving source of described heat pump, the delivery port of described heat pump connects the water inlet of attemperater, the delivery port of described attemperater connects the water inlet end of total water valve, the water inlet end of the described minute family water meter of water outlet termination of described total water valve.

Between described total water valve and branch family water meter, be serially connected with pressure pump.

Between described heat pump and attemperater, be serially connected with circulating pump.

Be provided with a return pipe at the hot water user place away from the attemperater water side, described return pipe is connected with attemperater, is serially connected with an electric control valve in return pipe.

Described house lead in device comprises that the branch family water meter of serial connection and branch family water valve constitute.

On described attemperater, be provided with the electronics water level controller.

The utlity model has advantage simple in structure, with low cost, that be suitable for popularization.
