Abstract
The utility model relates to a secondary exchange device for a heat pump. A secondary cooling device is mounted between a heat exchanger and a throttle in a refrigerant circulating system; and a temperature control valve is mounted between the input end and the output end of the secondary cooling device through a pipeline. The refrigerant circulating system for the heat pump is provided with the secondary cooling device and the temperature control valve; when the temperature of a refrigerant after being exchanged by the heat exchanger is higher than 40 degrees, the temperature control valve is closed; and after being cooled by the secondary cooling device, the refrigerant enters the circulating system through the throttle, so that the load of a compressor is reduced. When the temperature of the refrigerant after being exchanged by the heat exchanger is lower than 40 degrees, the temperature control valve is opened and the refrigerant directly enters the circulating system without passing through the secondary cooling device; because the secondary cooling device is automatically controlled by adopting the temperature control valve, the refrigerant can release after heat which is not released during the heat exchange, so that the working load of the compressor is reduced, the operation is stable, the service life is prolonged, and the water temperature can be heated up to 70 degrees.
Description
[technical field]
The utility model belongs to the cooling and warming technical field, relates to a kind of heat pump secondary switch that adopts the secondary cooling.
[background technology]
Heat pump techniques is based on a kind of energy-saving and environmental protection of setting up against the Carnot cycle principle and heats technology.Utilize the Teat pump boiler of this technological development, more and more be subjected to liking of people.The existing general heating-up temperature of Teat pump boiler is in 50-60 degree scope, as on the pipeline behind the heat exchanger, the temperature that still can record refrigerant is higher, and when temperature reaches 40 degree when above, the electric current of compressor can increase along with the rising of temperature, rising along with water temperature, the temperature of refrigerant also increases thereupon, and its rate of heat exchange of the high explanation of temperature is low, power consumption is high, and the temperature height also can cause compressor load overweight in addition, influence the normal operation of compressor, also can shorten compressor service life for a long time.
[utility model content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides that a kind of energy consumption is low, efficient is high, speed is fast, security is good, consumptive material is low, environmental and can effectively prolong the compressor heat pump secondary switch in service life.
The technical method that its technical problem that solves the utility model adopts is: a kind of heat pump secondary switch, between heat exchanger in coolant circulating system and the flow controller secondary cooling apparatus is installed, and between the pipeline of going into end and going out to hold of this secondary cooling apparatus, is connected and installed with temperature-sensing valve by pipeline.
Described coolant circulating system mainly contains compressor, evaporimeter, flow controller and heat exchanger.
The beneficial effects of the utility model are: the heat pump coolant circulating system is installed secondary cooling apparatus and temperature-sensing valve, when the temperature of refrigerant after heat exchanger exchange is higher than 40 when spending, temperature-sensing valve cuts out, and refrigerant enters the circulatory system by flow controller after the secondary cooling apparatus cooling, and compressor load alleviates; When the temperature of refrigerant after heat exchanger exchange is lower than 40 when spending, temperature-sensing valve is opened, refrigerant directly enters the circulatory system without secondary cooling apparatus, automatically control secondary cooling apparatus owing to adopt temperature-sensing valve, can make refrigerant discharge the waste heat that in heat exchanging process, has not discharged, can alleviate the operating load of compressor, help stable and prolong its service life, and can make the water temperature heating rise to 70 degree.The utlity model has the advantage of energy-conserving and environment-protective, thermal efficiency height, reliable and long service life.
[description of drawings]
Fig. 1 is a block diagram of the present utility model.
Among the figure: 1-compressor, 2-evaporimeter, 3-flow controller, 4-heat exchanger, 5-secondary cooling apparatus, 6-temperature-sensing valve.
[specific embodiment]
Below in conjunction with drawings and Examples the utility model is further specified:
Referring to Fig. 1, a kind of heat pump secondary switch is equipped with secondary cooling apparatus 5 between heat exchanger 4 in coolant circulating system and the flow controller 3, and is connected and installed with temperature-sensing valve 6 by pipeline between the pipeline of going into end and going out to hold of this secondary cooling apparatus 5; Described coolant circulating system mainly contains compressor 1, evaporimeter 2, flow controller 3 and heat exchanger 4.
In actual applications, when the refrigerant in the coolant circulating system rises to 40 when spending in temperature after heat exchanger 4 exchange, temperature-sensing valve 6 cuts out automatically, refrigerant can only enter the circulatory system by flow controller 3 from secondary cooling apparatus 5 cooling backs, compressor 1 load reduction, when the temperature of refrigerant after heat exchanger 4 exchange is lower than 40 when spending, temperature-sensing valve 6 is opened, refrigerant directly enters flow controller 3 by temperature-sensing valve 6 without secondary cooling apparatus 5 and enters the circulatory system again, owing to adopt the secondary cooling and adopt temperature-sensing valve 6 automatic control switch, can improve the operating load of compressor 1, help stable and prolong its service life, the utlity model has energy-conserving and environment-protective, thermal efficiency height, reliable, the advantage that long service life and consumptive material are low.
