Abstract
The invention discloses a kind of air-conditioning with defrosting function, including the defrosting device being arranged in air-conditioning, between the outlet of the exhaust outlet and evaporator of defrosting device bypass to compressor.The present invention, which is used, increases the method for defrosting device in air-conditioning system evaporator lower part, so that air-conditioning equipment is kept normal refrigerating operaton at relatively low ambient temperatures, meets the normal operation of some precision instruments, equipment.
Description
Technical field
The present invention relates to air-conditioning equipment field, specifically a kind of air-conditioning with defrosting function.
Background technique
Usually only when 24 DEG C of environment temperature or more, people just will use the refrigerating function of air-conditioning equipment, at present
Not only people needs using air-conditioning, and many precision instruments, equipment must also work just in the environment of low temperature can guarantee normal work
Or machining accuracy.Calorific value is big at work for these precision instruments, equipment, when environment temperature is lower than 24 DEG C, these accurate instrument
The heat that device, equipment issue still can make the temperature of surrounding be increased to the degree that they work that influences.This just needs to open air-conditioning
Equipment refrigeration, it is suitable for the temperature of their work or less that the operating ambient temperature of precision instrument, equipment, which is dropped to,.But ambient temperature mistake
In the case where low, the frosting of A/C evaporator surface will cause using air conditioner refrigerating for a long time, influence air conditioner refrigeration effect, final shadow
Ring the work for arriving air-conditioning.
The object of the present invention is to provide a kind of air-conditionings with defrosting function for summary of the invention, to solve prior art air-conditioning
Frosting influences the problem of air-conditioning works normally.
In order to achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of air-conditioning with defrosting function, it is characterised in that: including the defrosting device being arranged in air-conditioning, defrosting device into
For mouth by the exhaust outlet bypass of compressor in pipeline and air-conditioning, the outlet of defrosting device passes through evaporator in pipeline and air-conditioning
Outlet bypass.
A kind of air-conditioning with defrosting function, it is characterised in that: the defrosting device is to be integrated in air-conditioning evaporation
The defrosting pipeline of device lower part, defrosting pipeline one end is as import, and the other end is as outlet.
A kind of air-conditioning with defrosting function, it is characterised in that: accessing in the defrosting device inlet ductwork has
Solenoid valve.
A kind of air-conditioning with defrosting function, it is characterised in that: the solenoid valve, which is equipped in detection solenoid valve, to flow
The temperature sensor of temperature, temperature sensor are connect with the signal input part of air-conditioning computer controller, air-conditioning computer controller
Signal output end connect with solenoid valve.
The present invention increases defrosting device of the bypass mechanism as air-conditioning in air-conditioning, and the synthesis of this defrosting device is being steamed
The lower part of device is sent out, import is connect by pipeline with exhaust outlet of compressor, and outlet is connect with the outlet of evaporator, in inlet ductwork
Upper one solenoid valve of setting carries out switch control.The signal that air-conditioning computer controller is detected by temperature sensor is to solenoid valve
Switch is controlled.
The beneficial effects of the present invention are embodied in:
1) present invention makes air-conditioning equipment increase defrosting device, solves air-conditioning equipment and is able to maintain normal refrigeration at low ambient temperatures
The problem of operation.
2) present invention only increases a bypass mechanism in the refrigeration system of air-conditioning equipment, and the mechanism is by pipeline and electromagnetism
Valve group is at increased costs are not high.
Detailed description of the invention
Fig. 1 is a kind of air-conditioning system structure chart with defrosting function.
Fig. 2 is defrosting device position view.
In figure: 1- compressor, 2- defrosting import bypass line, 3- evaporator, 4- defrosting device, 5- temperature sensor, 6-
Defrosting exports bypass line, 7- air-conditioning computer controller, 8- solenoid valve.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
As shown in Figure 1, a kind of air-conditioning with defrosting function, including the defrosting device 4 being arranged in air-conditioning, defrosting device
By the exhaust outlet bypass of compressor 1 in pipeline 2 and air-conditioning, the outlet of defrosting device 4 passes through pipeline 6 and sky for 4 import
The outlet bypass of evaporator 3 in tune.
The main body of defrosting device 4 is when evaporator 3 designs, and the defrosting pipeline for being integrated in 3 lower part of evaporator exists in advance.
As shown in Fig. 2, including 6 groups of branches in evaporator 3, wherein branch a, b, c, d, e is the refrigeration liquid separation pipeline of evaporator, most lower
The branch f of side is defrosting pipeline.Since defrosting device is integrated in A/C evaporator, and solenoid valve is small in size, as sky
The bypass line of adjusting system is fully able to be integrated in air-conditioning.
The solenoid valve of refrigerant flow line on-off when defrosting device further includes control defrosting, access air-conditioning refrigeration system,
And the copper pipe of defrosting pipeline and solenoid valve is connected, defrosting device both ends can have defrosting with the tee tube of access system pipeline
Whether the air-conditioning control panel and detection evaporator of function reach the temperature sensor of defrosting condition.
The lower part of evaporator 3 of the synthesis of defrosting device 4 in air-conditioning.
Connection access has solenoid valve 8 on the pipeline of 4 import of defrosting device.
Solenoid valve 8 is equipped with the temperature sensor 5 of fluid temperature (F.T.) in detection solenoid valve 8, temperature sensor 5 and air-conditioning computer control
The signal input part of device 7 processed connects, and the signal output end of air-conditioning computer controller 7 is connect with solenoid valve 8.
Working principle of the present invention and process are as described below: starting air-conditioning equipment work first, when temperature sensor 5 measures
When the defrosting value of the too low arrival setting of the temperature of evaporator 3, by signal feedback to electric-controlled plate 7, electric-controlled plate 7 issues instruction, electromagnetism
Valve 8 is opened, and is partially entered and is melted through solenoid valve 8 from defrosting import bypass line 2 from the high temperature Freon gas that compressor 1 is discharged
In white device 4, the frost condensed on evaporator 3 will be melted by entering the inner high-temperature gas of defrosting device 4, in defrosting device 4
High temperature Freon gas, then because being sucked away heat liquefaction is freon liquid, is exported via defrosting and is bypassed during defrosting
Pipeline is sucked back by compressor 1, and so circulation is repeatedly until defrosting terminates；When the temperature that temperature sensor 5 measures evaporator 3 arrives
Up to setting defrosting end value when, by signal feedback to electric-controlled plate 7, electric-controlled plate 7 issues instruction, and solenoid valve 8 is closed, air-conditioning defrosting
Terminate.During defrosting, refrigeration is run air-conditioning as usual, and air-conditioning equipment is just realized in defrosting during refrigerating operaton
Function.
