The Advantages Of Temperature Adjusting Dehumidifier

The temperature adjusting dehumidifier has the following advantages


The temperature-adjusting dehumidifier is a kind of  equipment that can provide indoor heating, cooling and dehumidification at different indoor and outdoor temperatures. In order to meet the requirements of indoor temperature and humidity for pipeline thermal control, it has the following advantages:

1. Cooling dehumidifying  model

When the indoor temperature and humidity are high, the indoor cooling load is large, and the system operates in the cooling and dehumidifying mode. The four-way valve is electrically neutral, the cooling mode of the system operation, the solenoid valve of the indoor branch closes the second heat exchanger, the outdoor heat exchanger of the condenser, and the heat exchanger of the first indoor evaporator. The indoor air is cooled and dehumidified only by the first indoor heat exchanger, and the indoor temperature and humidity are still low. In this mode, you can also adjust the air or water outdoor heat exchanger to further adjust the cooling capacity, remove moisture, and increase the cooling capacity and water condensation rate while increasing the outdoor heat exchanger air or water.

(2) Temperature modulation mode

When the indoor humidity and humidity load are high, and the indoor cooling load is small, the system operates in temperature modulation mode. When the four-way valve is electrically neutral, the system is still running in the cooling mode, the outdoor heat exchanger and the second heat exchanger are two parallel capacitors, and the indoor heat exchanger of the first evaporator. The indoor air is cooled and dehumidified by the first indoor heat exchanger, passing through the room when the second heat exchanger condenses part of the heat, and then reheats the air inside. In this mode, the air volume of the outdoor heat exchanger and water can also be adjusted to adjust the heat transfer distribution of the two condensers, and further control the indoor heat, so as to achieve the purpose of controlling the indoor air temperature.

(3) Heating and dehumidifying mode

When the indoor humidity and humidity load are high, but the indoor temperature is low and the heat load is small, the dehumidification system operates in a warming mode. The four-way valve is electrically neutral, and the system operates in a cooling mode. The branch of the outdoor heat exchanger is the solenoid valve closed, the second heat exchanger condenser, and the indoor heat exchanger of the indoor first evaporator. Because of the high temperature refrigerant flow in the indoor 2 second heat exchanger, the indoor air in the indoor first heat exchanger and cooling and dehumidification, the overall condensation heat in the second heat exchanger room is used for reheating the air. In this mode, the refrigerant flow of the outdoor heat exchanger is cut off, and the condensation heat is taken by the indoor and the heat of the second heat exchanger (the heat of evaporation and condensation), so the air humidity treatment temperature rises and falls.

(4) Heating mode

When the indoor temperature is very low and the heat load is large, although the relative humidity is high, the water content is very low, and it is more difficult to remove the moisture in the air. The indoor temperature and humidity can be controlled by running the heating system. The four-way valve is electrified, the heating mode of the system operation, the solenoid valve of the second indoor heat exchanger is closed, the outdoor heat exchanger of the evaporator, and the heat exchanger of the first indoor condenser. Afterwards, in this mode, the indoor air transfers heat inside the first heat exchanger indoors without the second heat exchanger in the room. Increase and humidity decrease the temperature of the air, thus achieving indoor temperature and humidity control. 

(5) Automatic thawing

When the system is in model (1)-(3), the first indoor heat exchanger evaporator, the surface temperature of the evaporator is lower than 0 degrees Celsius, the relative humidity of the air entering the evaporator is high, and the moisture in the air will be on the outside of the evaporator. Face cream, when the cream reaches a certain thickness, the air side pressure loss, the updraft is reduced, the heat exchange effect is poor, and defrosting is required. At this point, to make the unit run in wet heating mode,the first heat exchanger condenser indoors, after the high temperature refrigerant enters the frost and melts quickly, returning to the original operating mode.

When the system is in the heating operation mode (4), the heat exchanger of the outdoor evaporator, the outdoor air temperature and low humidity and high evaporator surface temperature are lower than 0 ℃, the outer surface of the outdoor heat exchanger may also be frost. When the frost reaches a certain thickness, make the unit run in temperature modulation mode (2). Outdoor heat exchanger condenser, high temperature refrigerant enters the cream to melt rapidly, indoor second heat exchanger condenser, preventing the first heat exchanger inside, and the ooling air is directly into the room. After the frost is completely eliminated, the heating temperature mode is restored.
