The refrigeration work flow process of air-conditioning system is: compressor is compressed into cold-producing medium the gas of HTHP; The liquid that is condensed into HTHP through fin condenser gets into reservoir; Handle after liquid supply electromagnetic valve, expansion valve become the liquid throttling of HTHP the liquid of low-temp low-pressure through device for drying and filtering; The entering evaporator fin gasifies and becomes the gas of low-temp low-pressure, after gas-liquid separator separates the small amount of liquid in the return-air, gets into compressor, so periodic duty again.The air of centrifugal blower after with cooling of indoor evaporator fin and dehumidifying sent into the textile laboratory; Axial flow blower with the heat of outdoor fin condenser to outdoor discharge.
Air-conditioning system of the present invention has the mode of operation of humidity and temperature, humidity and temperature in its humidifier and the heater conditioning chamber, and setting the unit temperature accuracy is ± 0.5 ℃, the humidity precision is ± 1%;
Adopt the humidity mode of priority, when humidity during greater than setting value, unit carries out dehumidifying work, and open the temperature-compensating of electrical heating proportional quantities this moment when temperature is lower than setting value, as the back indoor humidity that dehumidifies is when being lower than setting value, and beginning proportional quantities humidification compensates; When humidity during, when temperature also is lower than setting value, directly open humidifier proportional quantities humidification, and carry out the compensation that heats up of electrical heating proportional quantities less than setting value; When humidity less than setting value, temperature is during greater than setting value, compressor and starting is freezed, humidifier proportional quantities humidification and the electrical heating proportional quantities compensation that heats up simultaneously.The number that compressor is opened is controlled by humidity, and the humidity deviation is during near higher limit, and compressor is opened more than two or two, on the contrary one of compressor unlatching.
Unit is mainly by humidity control, when ambient humidity>when setting humidity, unit centrifugal blower 1 is opened with condensation fan 14; Liquid supply electromagnetic valve 7 is opened, and compressor 12 is opened the unit refrigerated dehumidification; The number that compressor is opened is controlled by humidity; The humidity deviation is during near higher limit, and the compressor of unlatching is just many more, otherwise few more.Electrical heating 3 this moment is by temperature control, and temperature is high more, and electrical heating is opened just few more.Set humidity 5 minutes when testing environment humidity is higher than, humidity magnetic valve 5 is opened, and unit gets into and removes wet condition, and it is additional by the electrical heating 3 of stepless energy adjustment that the temperature after the dehumidifying is on the low side.
< when setting humidity, electrical heating 3 is opened number and is controlled by humidity, and humidity is high more, and the electrical heating 3 of unlatching is just many more, otherwise few more when ambient humidity.This moment, compressor 12 was controlled start-stop by temperature.Temperature is low more, and compressor 12 is opened just few more, can not open.
At this moment, two kinds of situation a can appear in unit, temperature arrives earlier, and b, humidity arrive earlier.
The situation that a, temperature arrive earlier:
At this moment temperature is lower than design temperature, thus compressor according to logic, change by temperature control, in case indoor temperature is low excessively, when the temperature progressively close compressor that also descends.
It is after temperature drops to set point that electrical heating starts, and changes by humidity control at once, and humidity is high more, and electrical heating unlatching number is many more, after electrical heating at this moment opens, can offset the cold that compressor produces.If still for not reaching setting value, it is 100% that electrical heating is opened to humidity at this moment.After temperature recovery was on the set point, electrical heating was changeed again by temperature control, when temperature arrives maximum temperature, closes electrical heating.
The situation that b, humidity arrive earlier:
Temperature reaches setting humidity earlier, at this moment is regarded as humidity balance, and at this moment control logic aims at the temperature balanced logic from the dehumidifying logic; Compressor and electrically heated control all are to be controlled by temperature; Be that compressor is driven in the temperature higher position, temperature is hanged down and is just opened electrical heating, with reference to the logic of humidification part.
