After changing, the energy consumption of whole system than generally only reaches 3 or so.And handpiece Water Chilling Units need chilled water pump, chilled water pipeline, valve
The facilities such as door, water tank, installation complexity take up a large area.If using Hot Spare, there are the too small efficiency of every unit refrigeration duty to drop
Low problem, if when there is hostdown again using cold standby the problems such as standby cooling-water machine start-up course complexity overlong time.
Invention content
It is an object of the invention to overcome the above-mentioned problems of the prior art, and provide a kind of water cooling precision air conditioner combination
Dynamic heat pipe system.Cooling tower is used outside water cooling precision air conditioner unit room, avoids the deficiency of air-cooled precision air conditioner, has simultaneously
Precision air conditioner installation is simple, the little advantage of the flexible Hot Spare energy loss of indoor arrangement.Along with shared outdoor cooling tower
Power heat pipe air-conditioning is as supplement, energy saving and reliability being optimal, for the optimal selection of data center's refrigeration.
The present invention solves technical problem and adopts the following technical scheme that：
A kind of data center's refrigeration system, including cooling tower one, cooling tower two, cooling water pump, heat pipe air conditioner condenser, heat pipe are empty
Adjust evaporator, two-phase liquid pump, solenoid valve, precision air conditioner condenser, precision air conditioner evaporator, compressor, throttle valve and circuit control
System processed；The cooling tower one and two input terminal of cooling tower and output end are in parallel respectively；The cooling tower, cooling water pump, precision
Air-conditioning condenser is sequentially connected in series into air conditioning cooling water circuit in order；The cooling tower, cooling water pump, heat pipe air conditioner condenser are pressed
Sequence is sequentially connected in series into heat pipe chilled(cooling) water return (CWR)；The precision air conditioner condenser, throttle valve, precision air conditioner evaporator, compressor
It is sequentially connected in series into air-conditioning refrigeration system in order；The heat pipe air conditioner condenser, two-phase liquid pump, solenoid valve, heat pipe air conditioner evaporation
Device is sequentially connected in series into heat-pipe refrigerating system in order；When system operation precision air conditioner refrigeration mode, solenoid valve and two-phase liquid pump
It closes, compressor and throttle valve are opened；When system operation heat pipe air conditioner refrigeration mode, solenoid valve and two-phase liquid pump are opened, pressure
Contracting machine and throttle valve are closed, and above two pattern can switch over work according to environment and demand.
There are two circuit control systems described above, and temperature sensor is respectively induced the temperature of indoor and outdoors region,
According to the comparison of the two temperature values, selective operation precision air conditioner refrigeration mode and heat pipe air conditioner refrigeration mode.
The present invention data center's refrigeration system the advantages of be：1. using water-cooled condenser, changed compared to air-cooled condenser
The thermal efficiency is more preferable, whole Energy Efficiency Ratio higher, while solving excessive air-cooled condenser floor space and condenser and indoor unit
Apart from long the problem of can not installing；2. using power heat pipe air-conditioning auxiliary cooling, compressor operating time is reduced, was both reduced
The power consumption of refrigeration, and the running wastage of compressor is reduced, to extending the service life of compressor；3. water cooling precision air conditioner and dynamic
Power heat pipe air conditioner shares same set of cooling tower systems, and to the of less demanding of place, installation difficulty is very low.
