Integral type water cooler, wherein electric control gear environment wet and dry bulb temperature sensor, circulation of fluid out temperature sensor and
Stream controller composition is recycled, the parameter signal of sensor is mainly acquired, to control output signal, and for automatically switching work
Operation mode.
The working principle of the invention,
One, the initial stage
It is started to work by temperature identification burst, after circulating water fish heat-producing device carries out heat exchange first, circulating water temperature is increased,
Circulating water returns to water tank, and the temperature controller in water tank recognizes the temperature in water tank, will signal to the first solenoid valve,
If the temperature sensor in water tank is higher than setting, then the first solenoid valve may turn on, second solenoid valve is in close state.
Two, refrigerating state
First solenoid valve starts, and second solenoid valve is closed, and condensing agent goes out liquid and changes after the first solenoid valve by plate, in plate parallel operation
The recirculated water that refrigerant provides refrigerant water pump cools down, and refrigerant changes in interior absorption recirculated water or air in plate
Heat is simultaneously gasificated into steam, and is extracted and compressed by compressor, after compression, become high temperature, high steam be sent to it is cold
The condenser that high pressure is cooled to after condenser goes out liquid, then interior by changing after the decompression of the first solenoid valve into plate, gasifies again, absorbs quilt
The heat of cooling material.
Three, dehumidified state
After circulating water temperature decline, lower than after set temperature, the first solenoid valve closes the temperature sensor displays temperature in recirculated water
It closes, second solenoid valve is opened, and condenser goes out liquid and carries out cool-down dehumidification to humid air by finned-tube evaporator through second solenoid valve.
Four, heat-producing device off position
When heat-producing device it is out of service i.e. refrigerating circuit load (cooling capacity) be zero when, which can be used for individually dehumidifying.At this
Under kind operating condition, the loop dehumidification solenoid valve most of the time is in the open state, in order to avoid being changed due to finned tube exchanger
Thermal energy power deficiency causes compressor to return liquid, and another way controls the settable periodic make-and-break time of loop dehumidification solenoid valve of signal,
To control refrigerant flow by loop dehumidification finned tube exchanger, some another refrigerant is through refrigerating circuit from hot gas
By-passing valve and the first solenoid valve return to compressor.
Beneficial effects of the present invention: plate changes and is equipped with refrigerant in finned-tube evaporator, and recirculated water or sky can be absorbed
Heat in gas is simultaneously converted to steam, is conducive to be extracted by compressor and compress, is converted to the steam of high temperature and pressure；Or it can be with height
The air of warm high humidity carries out convective exchange, to realize dehumidifying；The opposite on-off of first solenoid valve, second solenoid valve, can control
System enters plate and changes or the flow of the refrigerant in finned-tube evaporator, so that control panel changes, the heat exchange of finned-tube evaporator
Amount, solenoid valve also act the effect of decompression；Hot gas bypass valve and the first solenoid valve mix tandem to plate again and change to mouth, can incite somebody to action
Extra cooling capacity recycling, the saving of resource；Hot gas bypass valve is set, it can be when being not necessarily to dehumidify, by hot-gas bypass part
Cooling capacity for reducing the air humidity of outside condenser, enhance the heat transfer effect of condenser.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
