Feizhong WKLFD series rooftop ac and heat unit is a full air system, which is a large and medium-sized air conditioning equipment that integrates refrigeration, heating, constant temperature and humidity, air purification and other functions. This type of rooftop packaged ac unit series integrates direct-expansion combined air conditioners and air-cooled heat pump technology, realizing the advantages of centralized comprehensive control of refrigeration and air conditioning. It has the characteristics of high efficiency, energy saving, simple system, and stable performance. The complete microcomputer control makes the air Performance and quality are under advanced control; the compression and condensation section of the unit is assembled by plates, and each functional section of the air treatment section adopts an aluminum alloy frame and high-pressure foamed double-wall structure. It has mature technology, flexible design, and diverse combinations of functional sections. It has the characteristics of simple installation and easy control.
This series of rooftop cetral air conditioner can be used for indoor air conditioning under various environmental conditions. It has multiple functions such as cooling, dehumidification, heating, humidification, ventilation, etc. It has a wide temperature control range and precise humidity control. This series of air conditioners are indispensable auxiliary equipment for scientific research, national defense, industry, agriculture, commercial services, etc. Due to its compact structure and the fact that the whole machine can be placed on the roof or the ground without occupying effective space, it is widely used in industrial places with high requirements for temperature and humidity such as machinery, chemicl industry, and electronics, as well as in comfortable air environments such as shopping malls, supermarkets, and conference room
Work Principle
Cooling Mode
The outdoor fin heat exchanger serves as a condenser, and the indoor fin heat exchanger serves as an evaporator. After the high-temperature refrigerant gas discharged from the compressor condenses into liquid in the outdoor fin heat exchanger, it is throttled and depressurized by the expansion valve. It becomes a low-temperature gas-liquid mixture and then flows into the indoor side fin heat exchanger. It absorbs heat and evaporates before returning to the compressor to complete a refrigeration cycle. At the same time, the return air (or fresh air) from the indoor side passes through the indoor side fins for heat exchange. The evaporator (evaporator in this case) is cooled down, and the processed cold air is sent into the room by the indoor side fan.
