Embodiment:
Water tank (K) can be arranged on the outside or the inboard of test cabinet (P), wherein puts into the initial temperature T of water
2Be 32 ℃, all outer thermal insulation material that is surrounded by of water lines that relates to and relevant valve thereof and pump.
The water condensation mode that tested refrigeration fan (B) adopts has:
1. what adopt is by the conventional type recirculated water cooling mode of Fig. 2 signal (CN 1417531A adopt be exactly the water-cooling pattern of this routine), two kinds of situations are arranged: if when establishing special-purpose micro pump in the refrigeration fan (B), start when it will be started shooting along with refrigeration fan (B) and simultaneously, so, when test: water pump (8) should cut out and bypass valve (11) unlatching; If when establishing special-purpose micro pump in refrigeration fan (B) does not have, so, when testing: water pump (8) should be opened and bypass valve (11) should be closed, to guarantee having circulating water flow to pass through in the water cooling coil pipe (14).Certainly, in the overall process of test, back-water valve (BWV) (7) and water intaking valve (9) are the state that is in unlatching all the time.------adopts the recirculated water cooling mode to freeze, usually with the volume settings that is filled with water in the water tank (K) in 8 liters (water holding volume of flush toilet cistern), prolongation along with cooling time, water temperature in the water tank (K) can increase, cryogenic temperature (ability) also descends thereupon, calculate with 8 liter water volume, effectively (utilizable) refrigeration duration was generally about 15 minutes for it.
2. what adopt is by the cold mode of very formalism Static Water of Fig. 3 signal (CN 1409054A adopt be exactly this unconventional water-cooling pattern): at this moment only need to open water pump (8), allow be full of water in the static water-cooled tube (15) and get final product, spirally coiled condenser (16) wherein is exactly to rely on this static water to carry out condensation work.Obviously, its refrigeration duration is to be limited too, yet its duration of effectively freezing is relevant with the volume size of Static Water cooling cylinder (15), usually can be greater than 15 minutes.In the overall process of test, back-water valve (BWV) (7) and water intaking valve (9) should be closed to appropriate.
To refrigeration fan (B) test refrigerating capacity the time, the machine indoor set (1) of changes in temperature transducer air conditioning is set in the heating condition state, the main hot blast of desire by blowing out by centrifugal fan (6), offset the process of the cold wind that refrigeration fan (B) blows out, measure the power consumption of changes in temperature transducer air conditioning, extrapolate refrigeration fan (B) at environment temperature T
1The time refrigeration work consumption.
Because the water-cooled medium is to be made of fixing water source, prolongation along with cooling time, the fixedly temperature rise at water source, cause its refrigerating capacity also along with reduction, therefore its refrigeration work consumption As time goes on, form downward trend, final purpose of the present invention is to calculate time dependent refrigeration work consumption curve, and extrapolate in about 15 minutes continuous cooling periods, had the meaning represented maximum refrigeration work consumption (when water temperature is in initial temperature T
2Stage during) with average refrigeration work consumption.The prediction equation of the instant refrigeration work consumption N (refrigeration) of tested refrigeration fan (B) is as follows:
N (refrigeration)=EN
