Amount 42 left side of triple valve is closed the right side and is opened, and water pump A and water pump B is started, so that cold end water circulation system 2 is run together with surface air cooler 3, hot end water
4 independent operating of the circulatory system, compressor 11 start, and fluorine machine system 1 brings into operation, under entire unit is in refrigeration mode, first
The aperture of analog quantity triple valve 22 is adjustable, therefore its aperture is adjusted when running temperature is close to setting value, until complete
A full left side is closed the right side and is opened, and realizes steady adjusting, prevents big temperature deviation；
In process of refrigerastion, 21 cold water of cold end water tank enters surface air cooler 3 and refrigeration is realized in extraneous heat exchange, then passes through second
The heat exchanger channels B of heat exchanger 15 backs into cold end water tank 21, heats up water in the heat exchanger channels B of the second heat exchanger 15 and heat exchanger channels
Refrigerant heat exchanger in A realizes that cooling backs into cold end water tank 21, and so circulation realizes refrigeration；Refrigerant after heat exchange is through compressor
High temperature and high pressure gas is formed after 1 compression, recycles the water for backing into hot end water tank 41 in First Heat Exchanger 13 with hot end water circulation system 4
In two channels exchange heat, realize cooling condensation, by heat storage in hot end water tank 41 (under normal circumstances, only need to hot end water
The circulatory system 4 heat exchange condensation, without opening the exhaust fan 7 of condenser, when temperature hot end water tank 41 when the temperature is excessively high, need
Starting condenser radiates condensation outward, and when excessively high temperature can not condense, will lead to pipeline inner refrigerant pressure change
By connecting 8 induction pressure of condensing pressure switch with exhaust fan 7, the exhaust fan 7 for controlling condenser is switched), hot end water tank 41 is stored up
Depositing heat can be used for heating adjusting temperature, when actual temperature is lower than set temperature, is stablized by switch with analog quantity triple valve and is adjusted
Section reduces temperature deviation, while having energy-saving effect.
When running temperature is lower than setting value, first switch valve 23 is closed, and 22 left side of the first analog quantity triple valve is closed the right side and opened, the
Two switch valves 43 are opened, and 42 left side of the second analog quantity triple valve is opened the right side and closed, and are started water pump A and water pump B, are made cold end water circulation system 2
Independent operating, hot end water circulation system 4 are run together with surface air cooler 3, and entire unit is under heating mode, the second analog quantity threeway
Valve 42 close to setting value adjusts its aperture with running temperature, until a complete left side is closed the right side and is opened, realize it is steady adjust, prevent
There is big temperature deviation；
In heating operations, cold end water circulation system 2 exchanges heat in the second heat exchanger 15 absorbs storage low temperature, needs to dehumidify
When, third switch valve 51 is opened, can be dehumidified；Therefore, regardless of the water pump A of the cold end water tank under refrigeration or heating mode
Always it is all running, can dehumidify at any time, while there is energy-saving effect.
If long-time causes 21 temperature of cold end water tank too low under heating mode, the operation of fluorine machine system 1 can be stopped；
And pass through the energy storage of cold end water tank 21 and hot end water tank 41, adjusting and switch by two analog quantity triple valves, the
One, the switch of second switch valve also can control the temperature of phjytotron after stopping fluorine machine system 1, realize energy conservation.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modification, equivalent replacement or improvement etc., should all be included in the protection scope of the present invention within mind and principle.
