The specific embodiment
The present invention is described in detail below by specific embodiment.
As shown in Figure 1, be control section schematic circuit diagram of the present invention, control system comprises: master control borad, temperature-sensing element (as thermocouple, humidity sensor), the wet element (as temperature sensor) of sense, power plate, display or display screen etc. or other similar (merging) device also can be half mechanical half-electron control systems.By the signal that temperature or humidity sensor obtain, after the CPU processing, give correlation module, so that the action of commander's associated components, associated components has signal feedback system, is used for parts are judged, controls whole system.
Refrigeration system has: refrigeration circulatory system A and freezing cooling cycle system C two parts, comprise compressor 3, condenser 4, device for drying and filtering 5, one or more capillary, refrigeration evaporator 6, refrigerating evaporator 8, also may have devices such as fan 61, heater, reservoir 81 and magnetic valve.It mainly give in the casing between the chamber needed cold is provided, perhaps reconcile the distribution of energy, perhaps utilize refrigeration (perhaps cold) to dehumidify.
Humidity cooling cycle system B comprises: humidifier, dehumidifying evaporimeter 7, fan 61, cold-storage device, heater and other additional device constitute.Wherein humidifier and dehumidifying evaporimeter 7 both can increase humidity and also can take on dehydrating unit and use; In this system some device can with parts such as refrigeration system shared compressor 3, condenser 4, device for drying and filtering 5, magnetic valve, capillary and reservoir 81; This humidity cooling cycle system B also can use second compressor 31, second condenser 41, device for drying and filtering 5 ', humidifier and dehumidifying evaporimeter 7, magnetic valve, cold-storage device, capillary, forms an independently humidification cooling cycle system; This humidity cooling cycle system B can also adopt the chemisorbed formulation and the automatic humidifying apparatus of automatic processing.The chamber replenished (or removal) humidity between it mainly gave in the casing.This cold-storage device generally is made of regenerator, and this regenerator and humidifier, dehumidifying evaporimeter 7 are combined closely.
Its operation principle is as follows:
When the user sets refrigerator room temperature and humidity by operational module, after the microprocessor of microprocessing unit is received the signal of operational module,, control display and show, with handled easily through handling.After user's design temperature or the humidity, microprocessing unit at first compares with setting value the signal data of seeking corresponding data and Current Temperatures and humidity sensor in database or program.
This device has refrigeration circulatory system A, humidity cooling cycle system B, three parts of freezing cooling cycle system C, when starting work, preferential refrigeration circulatory system A work is humidity cooling cycle system B work then, and minimum is freezing cooling cycle system C work; If temperature is higher, microprocessor is connected this refrigeration system corresponding component by power plant module, makes it work, makes indoor temperature drop to specified point.
If humidity is higher, the cold of regenerator is less, and microprocessing unit is connected this refrigeration system corresponding components (compressor, magnetic valve, fan etc.) by power plant module, makes it work, and the evaporimeter that dehumidifies this moment is started working, and regenerator begins to store cold simultaneously.Air is by the dehumidifying evaporimeter in the dehumidifying fan suction-chamber, reduce airborne moisture (the indoor cold of dehumidification system input this moment imports indoor heat into less than the external world), when regenerator stores enough colds when temperature (as: reach certain), this refrigeration system quits work, but the dehumidifying fan continues operation till humidity reaches control and requires the minimum point scope.If regenerator enough colds is arranged the time, microprocessor is connected corresponding dehumidifying fan work by power plant module and is reached the control requirement.
If temperature and humidity is all higher, if regenerator has enough colds, then dehumidifying only starts the dehumidifying fan work and dehumidifies, and the corresponding refrigeration system on-the-job satisfaction temperature refrigeration requirement that only require this moment.If the cold of cold-storage gas is less, then the microprocessor of microprocessing unit is alternately connected two refrigeration systems by power plant module, promptly connects corresponding components, makes it operation, and adjusts by the speed that its temperature descends, till reaching the control claimed range.
If refrigerating chamber needs cold, whether the microprocessor judges regenerator of microprocessing unit stores cold needs to replenish; If desired, then allow, so that remove the certain cold of regenerator storage that humidity is used except that the work of humidity evaporimeter refrigeration system.After regenerator stores enough colds, the freezing cooling cycle system of isolated operation again.If do not need, the freezing cooling cycle system of isolated operation then.
When the frost that removes the humidity device or water reach a certain amount of (use the sensor data monitored and through the microprocessor judges of microprocessing unit), controller is connected corresponding heater work by power plant module, causes this system's defrost and discharges unnecessary defrost water.
If humidity is lower, heater and fan that controller is connected in the corresponding psychrometric means by power plant module are worked (storing more defrost water and frost in the psychrometric means) simultaneously, with the compensation indoor humidity.(because the constantly inflow of access food and extraneous moisture, indoor defrost water is always more than the water yield of humidification requirement).During humidification, the desiccant cooling circulation does not participate in work.
