The valley wheel fan unit usually refers to a valley wheel air-cooled unit, which is an efficient and reliable refrigeration equipment. The following is its introduction:

Structural composition

It is generally composed of a fully or semi enclosed refrigeration compressor, a high-efficiency copper tube aluminum plate condenser, a liquid reservoir, pressure control, pressure gauge, filter, solenoid valve, junction box, and fan.

working principle

The working principle of the valley wheel fan unit is the same as that of a general refrigeration cycle. The compressor sucks in low-temperature and low-pressure refrigerant vapor from the evaporator, compresses it into high-temperature and high-pressure superheated vapor, and then discharges it into the condenser. In the condenser, the refrigerant superheated vapor is cooled and condensed into liquid by dissipating heat to the surrounding air under the action of the fan. The liquid refrigerant enters the evaporator after being throttled and depressurized by the expansion valve. It absorbs heat and evaporates in the evaporator, becoming low-temperature and low-pressure refrigerant vapor, which is then sucked in by the compressor again. This cycle achieves refrigeration.

Performance characteristics

-Efficient and energy-saving:The energy efficiency ratio of the valley wheel compressor is high, and under the same refrigeration demand, the energy consumption is relatively low, which can reduce operating costs.

-Reliable operation:The compressor has fewer moving parts and adopts patented flexible design in both axial and radial directions, which has strong resistance to liquid impact and impurities, reducing the probability of failure and extending the service life of the unit.

-Low noise:The compressor runs smoothly with minimal vibration, coupled with a reasonable structural design and high-quality component selection, resulting in minimal noise generated during operation, making it suitable for environments with high noise requirements.

-Wide applicability:Multiple refrigerants such as R22, R404A, R507A, etc. can be used, with an evaporation temperature range from -50 ℃ to 12.5 ℃, which can meet the needs of different refrigeration applications, such as high temperature, medium temperature, and low temperature refrigeration systems in food, pharmaceutical, chemical, preservation, quick freezing, refrigeration, air conditioning and other fields.

-Easy maintenance:The unit has a compact structure, beautiful appearance, and easy installation. And the components of each model of unit in the series have strong universality, easy interchangeability and maintenance, reducing maintenance costs and difficulties.

application area

-Commercial refrigeration:Widely used in supermarkets, convenience stores, hotels, restaurants and other places as refrigerators, display cabinets, cold storage and other equipment, for the refrigeration and freezing preservation of food, beverages, fruits and vegetables.

-Industrial refrigeration:In industries such as chemical, pharmaceutical, and electronics, providing a low-temperature environment for process cooling and raw material storage during production ensures smooth production and stable product quality.

-Air conditioning system:Some valley wheel fan units can serve as cold sources for air conditioning systems, providing comfortable indoor air conditioning environments for buildings, office buildings, hospitals, schools, etc.
