Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, hereinafter with reference to the accompanying drawing in the embodiment of the present invention, by embodiment, technical scheme of the present invention is described clearly and completely, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The schematic diagram of the computer-room air conditioning system that Fig. 1 a provides for the embodiment of the present invention one.A kind of computer-room air conditioning system that the present embodiment provides, comprises refrigeration part 110 and humidifier 120, also comprises: heat exchanger 130.Heat exchanger 130 is provided with refrigerant input, refrigerant output, water body input and water body output, and refrigerant input is connected with the refrigerant exit end of refrigeration part 110, refrigerant output is connected with the refrigerant entrance point of refrigeration part 110, water body input is connected with water source 140 and water body output is connected with water inlet end with the humidification of humidifier 120.Heat exchanger 130 carries out heat exchange process for the humidification water of the refrigerant that transmits refrigeration part 110 and reception, and the refrigerant reducing temperature is transferred to refrigeration part 110, and the humidification water of raised temperature is transferred to humidifier 120.
As mentioned above, computer-room air conditioning system comprises the refrigeration part 110 for freezing and the humidifier 120 for humidification, and refrigeration part 110 dehumidifies to machine room in process of refrigerastion, and humidifier 120 pairs of machine rooms carry out humidification, ensure that in machine room, humidity is normal, equipment can safe and stable operation.After computer-room air conditioning system is opened, the refrigerant that refrigeration part 110 transfers to heat exchanger 130 is specially and compresses through refrigeration part 110 the HTHP refrigerant produced, the temperature of this refrigerant can reach 70 ~ 80 DEG C, and common water source is from the beginning elected at the water source 140 of the humidification water of humidifier 120 usually as, the temperature at water source is generally 5 ~ 20 DEG C from the beginning.
It should be noted that, refrigerant is the cold-producing medium of refrigeration part 110, and refrigerant its state in the cyclic process of refrigeration part 110 is changed between gaseous state and liquid state, and the temperature of gaseous coolant can reach 70 ~ 80 DEG C.The temperature of liquid refrigerants is usually above the temperature at conventional water source, and therefore the gaseous coolant that provides of refrigeration part 110 or liquid refrigerants all can as the heat exchange energy.
When the State Transferring of refrigerant is gaseous state, refrigeration part 110 is provided with refrigerant exit end with refrigerant entrance point and is connected with heat exchanger 130 in the transmission pipeline of corresponding gaseous coolant, to make gaseous coolant transmit through refrigerant exit end, heat exchanger 130 and refrigerant entrance point, heat exchanger 130 utilizes and carries out exchange heat through gaseous coolant wherein to humidification water.When the State Transferring of refrigerant is liquid, refrigeration part 110 is provided with refrigerant exit end with refrigerant entrance point and is connected with heat exchanger 130 in the transmission pipeline of corresponding liquid refrigerants, and heat exchanger 130 utilizes the liquid refrigerants through higher temperature wherein to carry out exchange heat to humidification water.
Humidification water in the refrigerant and water source 140 of the HTHP of this heat exchanger 130 pairs of refrigeration parts 110 transmission carries out heat exchange process, then the high temperature of refrigerant can carry out preheating to the humidification water of lower temperature.After the heat exchange process of heat exchanger 130, the temperature of refrigerant reduces, the temperature of humidification water raises, and now the refrigerant that temperature reduces is transferred to refrigeration part 110 and the humidification water of raised temperature is transferred to humidifier 120 by heat exchanger 130.The lower power consumption of refrigeration part 110, the power consumption of humidifier 120 also reduce thus, and the total energy consumption of corresponding computer-room air conditioning system reduces, and has saved the energy.Exemplary, after heat exchanger 130 carries out heat exchange to the refrigerant of 70 ~ 80 DEG C and the humidification water of 5 ~ 20 DEG C, the temperature of humidification water can increase by 20 ~ 30 DEG C, and corresponding humidifier 120 can save the power consumption of about 30%.
