The lower compartment of shell 1 comprises between machinery compartment 1a, condensation 1c between 1b and evaporation.Compressor 2 is installed in the machinery compartment 2.Condenser 3 is installed between condensation in the 1b, so the refrigerant in heat exchange medium and the condenser 3 carries out heat exchange.
In condenser 3, heat exchange operation is based on that water-cooled valve and air-cooling finish.Cooling water becomes little water droplet particulate, and little water droplet offers condenser 3.Extraneous air flows between condensation and offers condenser 3, and be used for condenser 3 in refrigerant carry out heat exchange.
To describe heat exchange medium in detail below.
As heat exchange medium, cooling water and extraneous air are arranged.Chilled water storage is in the chilled water storage jar.Supersonic oscillations plate 20 is installed in the bottom of chilled water storage jar 10, is used for cooling water being become little water droplet particulate and spraying to condenser 3.
In addition, air conduit 11 is installed in the chilled water storage jar 10, is used for spraying the water droplet particulate to condenser 3 effectively, and it is by the oscillator 21 change states of supersonic oscillations plate 20.Form through hole 22 in the supersonic oscillations plate 20.Air conduit 11 is by through hole 22.
Store a certain amount of cooling water in the chilled water storage jar 10.Level sensor " S " is installed in the chilled water storage jar 20.Controller " C " drives magnetic valve " V " based on the cooling water water level that level sensor " S " detects, thereby fills with the cooling water that is stored in the chilled water tank " T " again.
The air inlet 51 of air intake duct 50 is linked the outside, and exhaust outlet 52 be placed in chilled water storage jar 10 below, so extraneous air is through chilled water storage jar 10 and condenser 3.
Here, the part of exhaust outlet is from the next door process of air intake duct 50.Air-breathing and blast pipe 40 and 50 forms dual structure.The wall surface of structure forms the hole, so that two pipes 40 and 50 are installed, thereby realizes easier installation.
In addition, hair-dryer 60 is installed in the highest central part of guiding elements 30, thereby forces water droplet particulate and air circulation.Air circulation guide plate 70 is installed between hair-dryer 60 and the condenser 3, is used to guide air circulation.
Air circulation guide plate 70 tools have the dimensions, and are used to cover the top of condenser 3.Form circulation of air hole 71 on it.In the integral part of air circulation, form a plurality of circulations of air hole 71.

Therefore, the oscillator 21 of cooling water by supersonic oscillations plate 20 becomes and is little water droplet, is used for and the refrigerant that flows into condenser 3 inside carries out heat exchange.Because the water droplet particulate is too little, the water droplet particulate moves to each several part.Carry out the cooling water of heat exchange no longer reuses with the refrigerant of condenser 3.That is to say, use to have the suitable cooling water of temperature, so can keep the suitable temperature of refrigerant in the condenser 3.
The suction of hair-dryer 60 is applied on the extraneous air that water droplet and the circulation of air hole by air circulation guide plate 70 71 flow into, so water droplet and extraneous air offer the each several part of condenser 3.
Do not provide inner air to be used for carrying out heat exchange operation with the refrigerant of condenser 3.That is to say that in the present invention, thereby extraneous air is inhaled into and prevents that indoor temperature from raising.
As mentioned above, according to air regulator of the present invention, cooling water becomes the water droplet small particle and carries out heat exchange with the refrigerant of condenser.Because cooling water is no longer reused, and may keep the design temperature of the inside refrigerant of condenser.
In addition, the water droplet particulate is little and be injected into the each several part of condenser.That is to say that water droplet particulate and air are not parts that partly flows to condenser, therefore improved the condensation efficiency of condenser.
Because extraneous air is used as heat exchange medium, thereby can prevent that therefore the air themperature rising from having improved the reliability of air regulator.
Because the present invention can implement under the situation of not leaving its spirit or fundamental characteristics in a variety of forms, also should understand, the foregoing description is not that any details by above stated specification limits, unless otherwise defined, otherwise should in the spirit and scope that appending claims limits, broadly explain, therefore fall into the condition of claims and all changes in the boundary and the equivalent of correction or this condition and boundary and all will be included in appending claims.
