Machine coil pipe gives indoor refrigeration, and two evaporator coils are used to reduce and dehumidify to new air temperature, wherein the first evaporator plate is effective
In preliminary cooling, the second evaporator coil dehumidifies for deep temperature reduction, and fresh air is by after cool-down dehumidification, then passes through reheating coil pipe liter
Temperature processing is sent into the temperature and humidity that indoor fresh air reaches human comfort to allow.
Heating circulation
As shown in figure 3, heating up in winter by the new blower to the fresh air of feeding, while hot water is provided, the mode
The first port of lower first four-way valve and the second four-way valve is connected to the 4th port, and second port is connected to third port, twin-tub
Compressor sends out high temperature and high pressure gas and is divided into two-way two four-way valves of feeding, wherein the high temperature and high pressure gas that the first four-way valve comes out
It is divided into two-way, wherein being sent into the first evaporator coil all the way, primary heating is carried out to the low temperature fresh air of entrance, another way is sent into plate
Formula heat exchanger heats the water at low temperature being passed through, and forms hot water and sends out, and the high temperature and high pressure gas that the second four-way valve comes out is sent
Enter the second evaporator coil and reheating, the first evaporation gas coil pipe and the second evaporator coil are carried out to the fresh air after primary heating
It is cold that room temperature liquid refrigerants out forms gas-liquid two-phase after the first electric expansion valve and the second electric expansion valve reducing pressure by regulating flow
Matchmaker, and the gas-liquid two-phase refrigerant come out with electric expansion valve after plate heat exchanger collect being sent into condenser coil and be inhaled
Thermal evaporation forms gaseous coolant, the second port for dividing two-way to be respectively fed to the first four-way valve and the second four-way valve, and from third end
Mouth is sent to the air entry of duplex cylinder compressor, and a circulation loop is integrally formed.
In entire cyclic process, plate heat exchanger supplies radiating system or fan coil to interior for water to heat up
Heating, two evaporator coils, which are used to heat up to fresh air, guarantees that supply air temperature is suitable for, and wet-membrane humidifier is used to humidify to fresh air, protects
It is comfortable to demonstrate,prove blasting humidity.
