The solution adopted by the present invention to solve the technical problem is that:
After compressor cycle pipeline is connect with four-way reversing valve, a lateral line leads to after the first condenser and leads to the second condensation
Device, the second outside condenser be equipped with blower, the first condenser be equipped with thermal insulation board, one pipeline of four-way reversing valve with it is heat-insulated
The evaporator of plate lower part is connected to, and portion is equipped with drip tray under the vaporizers, and evaporator passes through Bidirectional expansion valve and the second condenser
Lower part connection, evaporator absorb heat by blower, and the first condenser and the second condenser are cooled down by blower.
Good effect: the present invention can reduce condenser by improving dehumidifier structure the air quantity with increase condenser
Temperature, improve the dehumidification efficiency of dehumidifier.It is suitable for being used as compression refrigerated dehumidification machine, air water machine.
Detailed description of the invention
Fig. 1 is structure composition figure of the present invention.
In figure, 1. compressors, 2. four-way reversing valves, the first condenser of 3.1., the second condenser of 3.2., 4. two-way expansions
Valve, 5. evaporators, 6. blowers, 7. drip trays, 8. thermal insulation boards.
Specific embodiment
Dehumidifier structure:
After 1 circulation line of compressor is connect with four-way reversing valve 2, a lateral line leads to after the first condenser 3.1 and leads to second
Condenser 3.2, the second outside condenser be equipped with blower 6, the first condenser be equipped with thermal insulation board 8, four-way reversing valve one
Pipeline is connected to the evaporator 5 of thermal insulation board lower part, under the vaporizers portion be equipped with drip tray 7, evaporator by Bidirectional expansion valve 4 with
The lower part of second condenser is connected to, and evaporator absorbs heat by blower, and the first condenser and the second condenser are carried out by blower
It is cooling.
The blower side is the function of evaporator heat absorption, while there are also the functions to condenser heat dissipation.
The blower is adjustable speed fan, can guarantee reasonable air quantity, improves dehumidifying rate.
Dehumidifying process:
High-temperature high-pressure refrigerant gas is discharged in compressor, enters four-way reversing valve through pipeline A, then enter the first condensation through pipeline C
Device.
Refrigerant carries out heat exchange with air in the first condenser, is tentatively condensed, after condensation, then through pipeline G into
Enter the second condenser.
Refrigerant enters the second condenser, by carrying out heat exchange with air in the second condenser, is condensed into high pressure
Refrigerant liquid.
Refrigerant liquid in condenser enters Bidirectional expansion valve decompression through pipeline M and becomes low-temperature low-pressure refrigerant, through pipe
Road N enters evaporator.
Refrigerant carries out heat exchange in evaporator with air, and refrigerant evaporation absorbs heat, becomes low temperature low pressure gas.
Dew point is dropped to by the air themperature of evaporator hereinafter, making the part water recovery Cheng Shui in humid air, into drip tray, from
And reduce the moisture in air.
Low-temperature low-pressure refrigerant enters four-way reversing valve through pipeline D, then enters the air entry of compressor through pipeline B, completes
One refrigeration cycle.
Here evaporator and the first condenser into are brought humid air respectively by the operating of blower, it is cold together enters second
Condenser.
The effect of thermal insulation board is: the heat transfer between condenser and evaporator is prevented, in order to avoid reduce effect on moisture extraction.
Defrosting operating:
High-temperature high-pressure refrigerant gas is discharged in compressor, enters four-way reversing valve through pipeline A, then enter evaporator through pipeline D.
High-temperature high-pressure refrigerant gas enters evaporator, and heat is discharged in evaporator, is condensed into liquid.Meanwhile to ice
Frost is heated, and frost becomes water, is discharged through drip tray.
Refrigerant liquid in evaporator enters Bidirectional expansion valve decompression through pipeline N and becomes low-temperature low-pressure refrigerant, through pipe
Road M enters the second condenser.
Refrigerant evaporates in the second condenser absorbs heat, becomes low temperature low pressure gas.The refrigerant of non-evaporating completely
Enter the first condenser through pipeline G further to evaporate, forms low-temp low-pressure gaseous refrigerant.
Low-temp low-pressure gaseous refrigerant enters four-way reversing valve through pipeline C, then enters the air entry of compressor through pipeline B,
Complete a defrosting circulation.
Technical principle:
Double-condenser is set in the circulatory system, condensation temperature is reduced by blower, evaporator absorbs heat under fan action,
Air themperature is dropped into the moisture in dew point or less absorption air；Condensation cycle air quantity is improved by double-condenser, reduces condensation
Temperature, to improve condensation effect.
Innovative point is: the mounting structure by changing evaporator and condenser increases the air mass flow of condenser, thus
Condensing pressure is reduced, effect on moisture extraction is improved.
Application example:
Dehumidifier is mounted on underground civil defense engineering, subway station, is operated by dehumidifier, can make workshop humidity reach 50% with
Under, to guarantee ambient humidity in the range of requiring.
Feature:
The refrigerant of compressor is condensed by the first and second two condensers in series, and the first condenser passes through heat-insulated
Plate connects evaporator, by the setting of condenser and evaporator, increases condenser air flow, reduces condensing pressure, improves cold
Solidifying effect, to improve effect on moisture extraction.By experiments have shown that, equipment dehumidifying rate standard condition higher than national standard 20% with
On.
