The invention has the following technical effects: 1. the dehumidifier can reduce the effective exhaust of the compressor and absorb heat of liquid refrigerant in the evaporator to decrease the heat exchanging ability of the evaporator; 2.the opening degree of the flow regulating valve can be automatically adjusted according to the predetermined outlet air temperature; 3. high temperature air enters the inlet of the evaporator to melt away frost on the evaporator; 4. when fresh air load is high and the overheating of a motor of the compressor is caused, the liquid refrigerant is sprayed on the motor to cool the motor.
Description
Technical field
The present invention relates to a kind of full fresh air temperature-adjustable dehumidifier, relate in particular to a kind of wide temperature range type full fresh air temperature-adjustable dehumidifier.
Background technology
At present, full fresh air temperature-adjustable dehumidifier normally is used through electric expansion valve, the electrodeless helical-lobe compressor of transferring, and adapts to the load variations that brand-new wind runtime environment variations in temperature causes; Regulate leaving air temp through Water flow adjusting valve.This system since the electrodeless helical-lobe compressor adjustable range of transferring between 25%～100%; When cause because of environment temperature is low new wind load be lower than compressor capacity 25% the time; Compressor can be shut down because of pressure of inspiration(Pi) is low, causes the unit frequent start-stop, influences control and job stability, the unit durability of air-out humiture; Even the Water flow adjusting valve of water-cooled condenser is transferred to maximum, leaving air temp can not be lower than EAT.When EAT was 27 ℃, its thermoregulation range was between 29 ℃～42 ℃, and the leaving air temp adjustable range is narrow; When new wind load is low, when causing evaporimeter frosting, need electrical heating to defrost, relatively power consumption; When new wind load is high, can make compressor motor overheating, compressor is at high temperature worked, and shortens the life-span.
Summary of the invention
The object of the present invention is to provide a kind of wide temperature range type full fresh air temperature-adjustable dehumidifier, this dehumidifier overcomes that existing full fresh air temperature-adjustable dehumidifier suitable environment temperature range is narrow, air-out humiture precision is not high, job insecurity and deficiency that can not automatic defrosting.
The present invention realizes like this; It comprises evaporimeter, device for drying and filtering, electric expansion valve, liquid spray valve, hot gas bypass valve, magnetic valve, gas-liquid separator, electrodelessly can transfer helical-lobe compressor, Water flow adjusting valve, water-cooled condenser, reservoir, flow control valve, check valve, air-cooled condenser; It is characterized in that evaporimeter connects gas-liquid separator, the gas-liquid separator connection is electrodeless can transfer helical-lobe compressor, and the electrodeless helical-lobe compressor of transferring connects hot gas bypass valve, magnetic valve and water-cooled condenser respectively; Water-cooled condenser is connection traffic control valve and air-cooled condenser respectively; Air-cooled condenser connects check valve, and check valve is connection traffic control valve and reservoir respectively, and reservoir connects liquid spray valve and device for drying and filtering respectively; Device for drying and filtering connects electric expansion valve; Electric expansion valve connects evaporimeter and hot gas bypass valve respectively, and the water inlet pipe of water-cooled condenser is connected with Water flow adjusting valve, and magnetic valve connects liquid spray valve.
Technique effect of the present invention is: one, can reduce effective exhaust of compressor, can absorb the heat of liquid refrigerant in the evaporimeter again, reduce the heat-exchange capacity of evaporimeter, make the pressure of inspiration(Pi) of compressor normal, thus operate as normal; 2, the open degree of flow control valve is regulated according to the air-out design temperature automatically; 3, when new wind load low, when causing evaporimeter frosting, hot gas bypass valve is open-minded, introduces part high-temperature high-pressure refrigerant gas from the high pressure chest of compressor, gets into evaporator, and the frost of evaporimeter is melted away; 4, when new wind load is high, make compressor motor overheating, be sprayed onto liquid refrigerant above the motor this moment, and motor is cooled off.
Description of drawings
Fig. 1 is a structural representation of the present invention.
In the drawings, 1, evaporimeter 2, device for drying and filtering 3, electric expansion valve 4, liquid spray valve 5, hot gas bypass valve 6, magnetic valve 7, gas-liquid separator 8, electrodelessly can transfer helical-lobe compressor 9, Water flow adjusting valve 10, water-cooled condenser 11, reservoir 12, flow control valve 13, check valve 14, air-cooled condenser
The specific embodiment
As shown in Figure 1; The present invention realizes like this; It comprises evaporimeter 1, device for drying and filtering 2, electric expansion valve 3, liquid spray valve 4, hot gas bypass valve 5, magnetic valve 6, gas-liquid separator 7, electrodelessly can transfer helical-lobe compressor 8, Water flow adjusting valve 9, water-cooled condenser 10, reservoir 11, flow control valve 12, check valve 13, air-cooled condenser 14; It is characterized in that evaporimeter 1 connects gas-liquid separator 7, gas-liquid separator 7 connects electrodelessly can transfer helical-lobe compressor 8, and the electrodeless helical-lobe compressor 8 of transferring connects hot gas bypass valve 5, liquid spray valve 4 and water-cooled condenser 10 respectively; Water-cooled condenser 10 is connection traffic control valve 12 and air-cooled condenser 14 respectively; Air-cooled condenser 14 connects check valve 13, and check valve 13 is connection traffic control valve 12 and reservoir 11 respectively, and reservoir 11 connects liquid spray valve 4 and device for drying and filtering 2 respectively; Device for drying and filtering 2 connects electric expansion valve 3; Electric expansion valve 3 connects evaporimeter 1 and hot gas bypass valve 5 respectively, and the water inlet pipe of water-cooled condenser 10 is connected with Water flow adjusting valve 9, and magnetic valve 6 connects liquid spray valve 4.Be used through electric expansion valve 3, hot gas bypass valve 5, the electrodeless helical-lobe compressor 8 of transferring, adapt to the load variations that brand-new wind runtime environment variations in temperature causes.When cause because of environment temperature is low new wind load be lower than compressor capacity 25% the time, 5 hot gas bypass valves are open-minded, introduce part high-temperature high-pressure refrigerant gas from the high pressure chest of compressor; Get into evaporator, like this, can reduce effective exhaust of compressor; Can absorb the heat of liquid refrigerant in the evaporimeter again; Reduce the heat-exchange capacity of evaporimeter, make the pressure of inspiration(Pi) of compressor normal, thus operate as normal.A flow control valve 12 is installed between the import and export of unit air-cooled condenser 14; When EAT was 27 °, when needs are adjusted to leaving air temp below 29 ℃, flow control valve 12 was opened; The part high-temperature high-pressure refrigerant gets into evaporimeter through flow control valve, and leaving air temp reduces.The open degree of flow control valve is regulated according to the air-out design temperature automatically.When new wind load is low, when causing evaporimeter frosting, hot gas bypass valve 5 is open-minded, introduces part high-temperature high-pressure refrigerant gas from the high pressure chest of compressor, gets into evaporimeter 1 import, and the frost of evaporimeter 1 is melted away.When new wind load is high, make compressor motor overheating, at this moment, liquid sprays valve 4, magnetic valve is open-minded, and liquid refrigerant is sprayed onto above the motor, and motor is cooled off.
