Description

Coolant natural circulation type unit air-conditioning unit
Technical field
The present invention relates to a kind of coolant natural circulation type unit air-conditioning unit, be specially adapted to cooling of mobile communication base station, high temperature freezer and other heat spaces occurred frequently.
Background technology
Along with the extensive use of mainframe computer and popularizing of mobile communication, machine room special machine equipment obtains widely applying.Because machine room special machine is the direct vaporation-type air-conditioning system of year round cooling operation, and general air conditioner refrigeration amount by summer the maximum cold load determine, even in winter of cold, when very low (outside temperature) still needed machine room, carry out refrigeration cool-down, but high frequent start and stop, the life-span of compressor is shortened greatly, the fault of air conditioner also can cause the rapid increase of room temperature simultaneously, often causes the fault of communications service.For addressing this problem, in the later stage seventies 20th century, Japan develops " refrigerant Natural Circulation and the kind of refrigeration cycle divergence type machine room special machine " that separate heat pipe and air conditioner are become one, as shown in Figure 1.This machine room special machine comprises that refrigerant Natural Circulation (being the heat pipe circulation) and mechanical refrigeration circulation are two independent loops loops, when outside air temperature is higher, adopt conventional compressor cooling circulation, when outside air temperature drops to a certain setting value, compressor is out of service, realizes indoor cooling cooling by the refrigerant Natural Circulation.Though this machine room special machine reliability and energy-saving effect obtain very big improvement, owing to need two groups of independently condenser and evaporimeters, cost costliness, resource cost are huge.
For improving machine room special machine cost height shown in Figure 1, the drawback that resource cost is huge, Daikin Industrial Co., Ltd was on the basis of compressor cooling circulation in 1985, on the air intake duct of the compressor 8 of compressor branch road 21, set up refrigeration magnetic valve 15, at compressor 8 and refrigeration magnetic valve 15 two ends heat pipe branch road 20 that has heat pipe magnetic valve 14 in parallel, liquid line magnetic valve 7 in parallel at throttling arrangement 12 two ends, develop separate heat pipe circulation is incorporated " coolant natural circulation type machine room special machine " in the compressor cooling circulation, as shown in Figure 2 (referring to: Sun Liying, horse is the best. the characteristic and the application of cryogen Natural Circulation air conditioner. and Harbin University of Commerce's journal (natural science edition), 2004,20 (6): 729-732.).This machine is when ambient temperatures such as transition season or winter are low, and by compressor out of service, the control mode of the refrigerant Natural Circulation that preferentially turns round can reduce power consumption significantly, has reduced the waste of unit material simultaneously again, has reduced manufacturing cost.
In " coolant natural circulation type machine room special machine " shown in Figure 2, still exist following defective can not guarantee security, reliability and the efficient operation of machine room special machine, be in particular in:
(1) adopted and opened and closed reciprocal heat pipe magnetic valve 14 and refrigeration magnetic valve 15, though can realize the switching of refrigerant kind of refrigeration cycle and Natural Circulation, but owing to adopt two magnetic valves, if the two one of break down, it is tight to cause a certain magnetic valve not open or close, and will cause the unit fault;
(2) since kind of refrigeration cycle during with Natural Circulation required refrigerant circulation different with charging amount, during natural-circulation operation, the liquid refrigerants major part is in evaporimeter 13, and during refrigerating operaton, the liquid refrigerants major part is in condenser 10.Present design feature is: guarantee that kind of refrigeration cycle efficiently moves, liquid refrigerants storage capability during then owing to Natural Circulation in the evaporimeter 13 is less than normal, evaporimeter 13 areas can not be fully used, so the operational efficiency of Natural Circulation is low, can utilize the time short, must increase kind of refrigeration cycle running time; Otherwise if guarantee that Natural Circulation efficient is higher, then refrigeration machine deposits in the condenser in a large number during kind of refrigeration cycle, causes condensing pressure very high, and operational efficiency is low.Therefore, the annual energy-saving effect of machine room special machine is not obvious.
(3) during the refrigerant natural-circulation operation, when gaseous coolant entered condenser 10, it was inner and deposit collection in the discharge chamber of compressor 8 still can to enter compressor 8 along compressor 8 blast pipes, and compressor 8 can liquid hammer occur when starting or oil hits phenomenon, causes compressor damage.
Therefore, press for and address the above problem, to realize the safe, reliable, efficient operation of coolant natural circulation type machine room special machine.
