Description
Technical field
What the present invention relates to is a kind of device of refrigeration technology field, specifically is a kind of evaporation cooling type constant temperature-humidity machine.
Background technology
At present, the constant temperature and humidity unit is widely used in the control occasion of industrial various ambient temperature and humidities.
Find Chinese patent title: " novel constant-temperature constant humidity unit ", application number: CN02217215.7 through literature search to prior art; Publication number: CN2542968, the unit that this patent proposes comprises compressor, condenser coil and the evaporation expansion gear that is connected by the refrigeration pipe arrangement, it is characterized in that described evaporation expansion gear is formed in parallel by two groups of magnetic valves that are connected in series successively, heating power expansion valve and evaporation coils.But, for this constant temperature and humidity unit, have following shortcoming: the first, not high at the cooling effectiveness of the cold-producing medium of condenser side; The second, the control ability of ambient humidity is also poor, and especially for the occasion that needs humidification, this constant temperature and humidity unit is more powerless.
Therefore, improving the cooling effect of the cold-producing medium of condenser side, and improve the control ability of unit to ambient humidity, is the problem of needing solution badly.
Summary of the invention
Deficiency and defective for overcoming prior art the present invention proposes a kind of evaporation cooling type constant temperature-humidity machine, make it adopt the vaporation-type cooling to improve the condenser heat exchange efficiency, adopt ultrasonic humidifier to satisfy the requirement of humidity control.
The present invention is achieved by the following technical solutions, and evaporation cooling type constant temperature-humidity machine of the present invention comprises: compressor, condenser, heating power expansion valve, evaporimeter, the water tank that catchments, water circulating pump, water pipe, spray thrower, outside-air intake, air-introduced machine, indoor return air inlet, electric heater, ultrasonic humidifier and blower fan.
Compressor outlet is connected with condenser inlet, and condensator outlet is connected with the heating power expansion valve import, and the thermal expansion valve outlet port is connected with evaporator, and evaporator outlet is connected with compressor inlet.Evaporation cooling type constant temperature-humidity machine is divided into two parts: condenser side and vaporizer side.
At condenser side, the water tank that catchments outlet is connected with the water circulating pump import by water pipe, and exit of pump is connected with the spray thrower import by water pipe.The water tank that catchments is positioned at the outside-air intake below, and its top position is a condenser, and the condenser top is a spray thrower, and the spray thrower top is an air-introduced machine.
At vaporizer side, evaporimeter is positioned at the top of indoor return air inlet, and the top of evaporimeter is an electric heater, and the top of electric heater is a ultrasonic humidifier, and the top of ultrasonic humidifier is a blower fan.
Gaseous refrigerant is sucked by compressor and the gas of boil down to HTHP, and high-temperature high-pressure refrigerant enters behind the condenser by the outer shower water evaporative cooling of pipe, pass through the throttling action of heating power expansion valve again after, send into the needs that evaporimeter satisfies user side.Leave the cold-producing medium of evaporimeter and get back to compressor at last again, carry out next one circulation.
At condenser side, outdoor air is from bottom to top sucked by air-introduced machine, and the water in the water tank that catchments is recycled water pump and delivers to spray thrower, and spray thrower is under the coil pipe spray of water facing to condenser.Because the effect of evaporation will be carried out heat exchange with the cold-producing medium in the pipe, make the cold-producing medium of HTHP obtain cooling at the shower water of coil surface.
At vaporizer side, indoor return air is under the effect of blower fan, cold-producing medium heat exchange through flowing in the evaporator plate tube and tube earlier, air after being cooled satisfies the requirement of indoor temperature again through the heat effect of electric heater, last air carries out certain humidification through ultrasonic humidifier, satisfies the requirement of indoor humidity.
Evaporation cooling type constant temperature-humidity machine of the present invention is compared with conventional constant temperature and humidity machine, it has adopted the vaporation-type cooling at condenser side, utilize evaporation of water to be used for the cold-producing medium of cooling down high-temperature high pressure, and adopted ultrasonic humidifier to realize the control of indoor humidity at vaporizer side, therefore, has good Temperature and Humidity Control effect.
