Unit principle:
Solid arrow is standard cooling flow；
Dotted arrow is natural cooling flow process；
1, compressor cooling (conventional refrigeration)
Seeing Fig. 1, summer, unit start ran, and generator set controller gathers the state of each sensor, opens 14 pressure fan
Judging that indoor temperature, whether more than design temperature+deviation, no will close the output (load) outside pressure fan, indoor temperature is more than and sets
Fixed temperature+deviation, continues to judge that outdoor temperature is less than or equal to design temperature and deducts-20 DEG C, owing to being summer so outdoor temperature
More than design temperature, so starting 1 compressor, start 20 cooling fans, unit refrigerating operaton.1 compressor is by refrigerant compression
Being transported to 2 oil eliminators, separated with cold-producing medium by lubricating oil at 2 oil eliminators, lubricating oil returns to compressor, and cold-producing medium entered 3
Stop valve 1 to 4 outdoor heat exchanger；At 4 outdoor heat exchangers, the gas of cold-producing medium High Temperature High Pressure is condensed into the liquid of middle temperature high pressure；
Refrigerant liquid flows into 6 reservoirs through 5 stop valves 2；6 reservoirs store unnecessary cold-producing mediums and by the cold-producing medium of gaseous state and
Liquid refrigerant separates, and is that to flow out is the cold-producing medium of pure liquid；Liquid refrigeration flows into 7 devices for drying and filtering, at device for drying and filtering
Middle impurity screening and moisture；Throttle through 9 expansion valves 1 and absorbed by exchanger heat exchange liquid refrigerant at 10 indoor heat exchangers
The heat of environment becomes the gaseous refrigerant of low temperature, reduces the air themperature through heat exchanger by the decalescence of cold-producing medium；
Gaseous refrigerant isolates the liquid refrigerant evaporated the most completely in 11 gas-liquid separators, and gaseous refrigerant returns to compressor
Carry out refrigeration work again.8 electromagnetic valve effects are 10 indoor heat exchangers to be divided into 2 branches, when ambient temperature has arrived at cooling
Requirement, but the humidity in room is also not reaching to control requirement, is lowered into the refrigeration of heat exchanger by reducing the area of heat exchanger
The temperature of agent reaches to control the purpose of humidity.
2, Cooling System
Winter, unit start ran, and generator set controller gathers the state of each sensor, opens 14 pressure fan and judges indoor
Temperature, whether more than design temperature+deviation, no will close the output (load) outside pressure fan, indoor temperature be more than design temperature+
Deviation, continues to judge that outdoor temperature deducts-20 DEG C less than or equal to design temperature, owing to being that winter is so outdoor temperature is less than setting
Temperature deducts-20 DEG C, unit starting 17 water pump, and water pump internal operation is 30% ethylene glycol solution (note for deionized concentration
The glycol concentration of this solution of anticipating determines according to local meteorological minimum temperature, looks into glycol concentration proportioning table low by freezing point temperature
In local area winter minimum temperature-10 DEG C, the freezing point of matched proportion density solution.During in order to prevent unit from running in the winter time the coldest
But the water freezing of internal system and can not flow).Solution water is flowed into 13 Indoor Natural cooling heat exchangers and carries out heat exchange by water pump
The solution water of inner cryogenic carries out heat exchange with indoor air, reduces the indoor air temperature through heat exchanger, absorbs
The temperature of the heat solution water of room air increases；Through 15 ratio three-way control valves, (effect of three-way valve is used to regulation
Enter the flow of the solution water of heat exchanger, thus carry out bar regulation and enter the heat exchange amount of Indoor Natural cooling heat exchanger, work as Indoor Temperature
Degree is more higher than design temperature, and three-way valve is just opened greatly, and closer to design temperature, three-way valve is the least with regard to aperture).Flow through 19 stop valves 4
To 12 outdoor natural cooling heat exchange devices, (effect with Indoor Natural cooling heat exchanger is contrary is discharged to outdoor by heat, reduces water-soluble
The temperature of liquid) open 20 cooling fans, solution flows through 18 stop valves 3 and 16 and expands fillings and return to water pump and complete heat transfer process.(swollen
Voltage stabilizing and the effect of part water storage are mainly played in the effect of swell, and the volume of the inside of expanding with heat and contract with cold of water can change, and is
Pressure within Tong also changes, and plays compensator or trimmer pressure fluctuation and the effect of part feedwater).Cooling System indoor unit and room
Outside unit is respectively arranged with a natural cooling heat exchange device, with pipeline, both is connected into closed loop.Working fluid is through indoor
During the heat exchange coil of side, heated by indoor air.Owing to the temperature working fluid after heating is higher than outside air temperature, when it
When circulating through the heat exchanger of outside, its heat is delivered to outdoor air, and temperature reduces.
Under this operating mode, being originally compressor cooling needs to consume substantial amounts of electric energy, and energy consumption is high, uses now natural cooling
System cools down, and the parts of operation only have water pump and 2 heat exchange blower fans, unit power consumption saving energy 70%.It is substantially reduced
The energy consumption of unit operation.
3, compressor cooling+Cooling System
When excessive season in spring and autumn, because the indoor and outdoor temperature temperature difference is little, indoor temperature can not be reduced with Cooling System
To when arranging temperature, open compressor cooling+Cooling System simultaneously.Principle is ibid.
Under this operating mode, open compressor cooling+Cooling System simultaneously, can because using natural cooling device to run
So that bigger cooling load can be born along with the change of temperature, the operation time of compressor cooling so can be reduced.Reduce
The energy consumption of unit operation, also extends the service life of compressor.
Natural cooling energy-saving constant-temperature constant-moisture air conditioning system is outdoor temperature is suitable when, it is achieved natural cooling, reduces
The working time of compressor, thus realize energy-conservation purpose.
In sum, above-mentioned embodiment is not the restricted embodiment of the present invention, all those skilled in the art
The modification carried out on the basis of the flesh and blood of the present invention or equivalent deformation, all at the technology category of the present invention.
