Description
The utility model relates to a kind of dehumidifier, especially a kind of automatic defrosting dehumidifier.
Dehumidifier is to adopt the method for the mechanical refrigeration water in air steam that condenses, and makes it condense into water droplet and is gathered in the water container.Because the dehumidifier fan drives air and constantly circulates, water in air divides constantly to be got off with fixed attention, dehumidifier is made up of parts such as refrigeration compressor, evaporimeter, air-cooled condenser, gas-liquid separator, liquid reservoir, magnetic valve, blower fan, expansion valve, control instrument and electrical controls, connects refrigeration compressor, condenser, magnetic valve, expansion valve, evaporimeter, evaporimeter respectively by the service pipe of cold-producing medium and connects refrigeration compressor again and constitute a kind of refrigeration cycle.The working range that dehumidifier is general is 18-32 ℃, and when dehumidifier is being lower than when moving under 18 ℃ of operating modes, evaporimeter tends to because surface temperature is lower than 0 ℃ and frosting can not normally move dehumidifier.Because the wide latitude that jumps in China region is very big, range of temperature is also very big, a lot of areas indoor temperature in winter is lower than 18 ℃, when dehumidifier moves under being lower than 18 ℃ of operating modes, evaporimeter meeting frosting because surface temperature is low, this frost layer can influence passing through of wind, influences effect on moisture extraction, at this moment must carry out defrosting to unit.
The purpose of this utility model is: a kind of automatic defrosting dehumidifier is provided, and it is that 5-18 ℃ area can operate as normal that this equipment can guarantee in indoor temperature.
The operation principle of the utility model dehumidifier refrigerant dehumidification system except that defrosting system and electric control system is identical with existing dehumidifier.When dehumidifier moves under being lower than 18 ℃ of operating modes, evaporimeter meeting frosting because surface temperature is low, this frost layer can influence passing through of wind, influences effect on moisture extraction, at this moment must carry out defrosting to unit.The utility model is the dehumidifier that defrosting device is housed.It is the evaporimeter defrosting that defrosting device starts under the control of automatic instrument(s) automatically.The principle of automatic defrosting device is by the pressure differential before and after the pressure difference meter measurement evaporimeter and can jointly controls by the temp probe measurement compressor return air that other is located on the muffler ancient piece of jade, round, flat and with a hole in its centre, when the evaporator surface frosting is arrived to a certain degree, pressure reduction between the pressure tap of pressure difference meter both sides strengthens, pressure difference meter action when reaching setting value, if the temp probe on this moment return-air tube wall records temperature and also is lower than setting value, controller will cut out main solenoid valve and open the defrosting magnetic valve and carry out the molten frost of hot gas automatically, when white melting layer arrives to a certain degree, pressure reduction between the pressure tap of pressure difference meter both sides is replied normal, pressure difference meter reset or the return-air tube wall on temp probe record temperature and also be higher than setting value, machine recovers the work that normally dehumidifies again, thereby guarantees dehumidifying function operate as normal between 5-18 ℃.This dual signal control system can be got rid of pressure difference meter and cause the defrosting system misoperation because of dirty reason such as stifled.
Dehumidifier is made up of parts such as refrigeration compressor, evaporimeter, air-cooled condenser, gas-liquid separator, liquid reservoir, magnetic valve, blower fan, expansion valve, control instrument and electrical controls, connects refrigeration compressor, condenser, magnetic valve, expansion valve, evaporimeter, evaporimeter respectively by the service pipe of cold-producing medium and connects refrigeration compressor again and constitute a kind of refrigeration cycle.The utility model is provided with connecting pipe between the outlet conduit of the outlet conduit of compressor and expansion valve, and on this pipeline, be provided with the defrosting magnetic valve, micro-pressure sensor is installed at the windward side and the back side at evaporimeter, and sensor control signal connects the work control coil of defrosting magnetic valve.
Further improvement of the utility model is: be provided with temperature sensor on a muffler ancient piece of jade, round, flat and with a hole in its centre, in order to measuring the temperature of compressor return air, and control the work control coil of defrosting magnetic valve simultaneously with above-mentioned micro-pressure sensor.
Characteristics of the present utility model are: the utility model can guarantee dehumidifying function operate as normal between 5-18 ℃, and the dual signal control device can be got rid of pressure difference meter and cause the defrosting device misoperation because of dirty reason such as stifled.
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment:
