Description
Technical field
The utility model relates to air-conditioning heat recovery technology field, especially a kind of air-conditioning recuperation of heat unit.
Background technology
Current, the Along with people's living standard improves constantly, skyscraper newly-built in a large number.Newly-built skyscraper must install air-conditioning system additional; But use common central air conditioner system to have following deficiency: a large amount of condensation heat directly enters atmosphere; Lose in vain, and surrounding environment is caused thermal pollution, and; The cooling system of central air-conditioning generally all disposes axial flow blower or cooling tower dispels the heat, and causes very big noise pollution and energy waste.
The utility model content
So enter atmosphere and cause the waste of the energy and the deficiency that heat radiation the time causes a large amount of noise pollution in order to overcome existing condensation, the utility model provides a kind of air-conditioning recuperation of heat unit.
The utility model solves the technical scheme that its technical problem adopted: a kind of air-conditioning recuperation of heat unit; Comprise compressor, outdoor heat exchanger, indoor heat exchanger, magnetic valve and four-way change-over valve; Pipeline between outdoor heat exchanger and the indoor heat exchanger is provided with check valve and expansion valve, and check valve and expansion valve parallel connection, is connected with heat recovering heat exchanger on the pipeline between compressor and the four-way change-over valve; And fluorine chlorine magnetic valve is connected in parallel on heat recovering heat exchanger refrigerant side import and export two ends; The delivery port of heat recovering heat exchanger is connected with boiler, and is provided with temperature sensor at the delivery port of heat recovering heat exchanger, and temperature sensor connects waterway electromagnetic valve.
The beneficial effect of the utility model is; This air-conditioning recuperation of heat unit; Be connected with heat recovering heat exchanger on the pipeline between its compressor and the four-way change-over valve, and the delivery port of heat recovering heat exchanger is connected with boiler, the water inlet of heat recovering heat exchanger is connected with water inlet pipe.Heat recovering heat exchanger is with high temperature.The superheated steam of high pressure cools off, is condensed into the liquid of high temperature, high pressure, simultaneously exhaust sensible heat and partial condensation latent heat is heated cold water, and the hot water that heated is kept in the boiler; Can provide life to use hot water at any time; Thereby a large amount of condensation heat obtained can be, effectively avoided the thermal pollution of air-conditioning to surrounding environment, temperature sensor detects the temperature of hot water;, temperature starts waterway electromagnetic valve when reaching critical point; Make hot water get into boiler, realize automatic operation, practiced thrift the energy.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the circuit diagram of the utility model;
Among the figure 1, the recuperation of heat converter, 2, pressure controller, 3, compressor, 4, outdoor heat exchanger; 5, check valve, 6, expansion valve, 7, indoor heat exchanger, 8, fluorine chlorine magnetic valve; 9, four-way change-over valve, 10, temperature sensor, 11, boiler, 12, waterway electromagnetic valve.
The specific embodiment
Like Fig. 1 is the structural representation of the utility model; A kind of air-conditioning recuperation of heat unit; Comprise compressor 3, outdoor heat exchanger 4, indoor heat exchanger 7, magnetic valve 8 and four-way change-over valve 9; Pipeline between outdoor heat exchanger 4 and the indoor heat exchanger 7 is provided with check valve 5 and expansion valve 6, and check valve 5 and expansion valve 6 parallel connections, is connected with heat recovering heat exchanger 1 on the pipeline between compressor 3 and the four-way change-over valve 9; And fluorine chlorine magnetic valve 8 is connected in parallel on heat recovering heat exchanger 1 refrigerant side import and export two ends; The delivery port of heat recovering heat exchanger 1 is connected with boiler 11, and is provided with temperature sensor 10 at the delivery port of heat recovering heat exchanger 1, and temperature sensor 10 connects waterway electromagnetic valve 12.
This air-conditioning heat recovery machine is when refrigerating operaton, and the refrigerant vapour of low-temp low-pressure is compressed into the superheated steam of HTHP through compressor 3, and row is to recuperation of heat converter 1; In recuperation of heat converter 1, cool off, be condensed into the liquid of HTHP, simultaneously exhaust sensible heat and partial condensation latent heat are heated cold water, the rich hot water temperature of heating can reach 45 ~ 60 ℃; Remain in the boiler 11; At any time providing life to use hot water, recuperation of heat converter 1 delivery port is provided with temperature sensor 10, when leaving water temperature during greater than 60 ℃; Fluorine chlorine magnetic valve 8 is opened; Cold-producing medium is without recuperation of heat converter 1, and through four-way change-over valve 9 to outdoor heat exchanger 4, condensation heat is discharged by axial flow blower or cooling tower in outdoor heat exchanger 4; When leaving water temperature less than 60 ℃ is, fluorine chlorine magnetic valve 8 cuts out, and cold-producing medium is through recuperation of heat converter 1; Condensation heat heating domestic hot-water passes through outdoor heat exchanger 4 again, and the refrigeration system high pressure side is provided with pressure controller 2; The rotating speed of the condensing pressure signal controlling axial flow blower goods cooling tower electric machine that it records is discharged remaining condensation heat, and temperature sensor 10 detects the temperature of hot water;, temperature starts waterway electromagnetic valve 12 when reaching critical point; Make hot water get into boiler, realize automatic operation, practiced thrift the energy.
