Air Cooled Chiller With R407C

　　Working principle of air-cooled chiller

　　Air-cooled chiller: A type of chiller that directly uses the air condenser on the unit to discharge heat into the air. Air-cooled machines are used in areas where water is scarce, or where it is inconvenient to receive water. There are mainly three interconnected systems: refrigerant circulation system, water circulation system, electrical automatic control system.

　　From the working principle diagram of the air-cooled chiller above, we can see that during operation, the refrigerant absorbs the heat of the object to be cooled (such as cooling water) in the evaporator and vaporizes, and the compressor continuously removes the generated gas from The vapor is extracted from the evaporator and compressed into high temperature and high pressure vapor. The refrigerant vapor is sent to the condenser for heat exchange with the air, and condensed into liquid after releasing heat. Absorb the heat of the object being cooled, and so on over and over again.

　　Features of air - cooled chiller

　　Air cooled chiller can be used in small systems, large units are mostly water cooled.

　　The air-cooled chiller adopts finned condenser, which directly takes away the refrigerant heat by the fan forced air flow without other auxiliary equipment, eliminating the cooling tower, cooling water pump and cooling pipeline system. It has certain advantages in installation, especially for small chiller with small refrigerating capacity requirements, and its convenient movement has great advantages.

　　Due to the different heat transfer temperature difference, in the same outdoor environmental conditions, the condensation temperature of the air-cooled chiller is higher than that of the water-cooled chiller, so the power consumption of the air-cooled chiller will be higher under the same cooling capacity. In terms of energy efficiency, the cooling capacity of water-cooled units is usually 300~500 Kcal/h higher than that of air-cooled units.

　　Air-cooled chiller avoids scaling of condenser and blockage of water pipe caused by poor water quality area, and saves water resources. However, the heat transfer efficiency of the finned condenser used is greatly affected by the accumulation of ash scale. Dust filter grids must be set before the heat dissipation finned tube, and regular cleaning is required.

　　Features of air cooled chiller:

　　1. Installation-free cooling water tower, easy to install, easy to move, suitable for places where there is no water source for installation-free water towers

　　2.Low noise fan motor, excellent cooling and condensation effect, stable throttling mechanism, excellent anti-rust treatment

　　3.Adopt high-performance compressor imported from Europe and America, with high EER value, low noise and stable operation. This product adopts a touch-type waterproof and dust-proof control panel, and the cooling temperature is adjustable from 3 to 30 °C. The contactor adopts international brands, the control system adopts modular design, and is equipped with multiple protection devices such as system acid-base protection, current overload protection, high and low voltage protection and time delay protection. If there is a fault, it will alarm and display the fault in time.

　　4.This product adopts a new original imported compressor, which makes the energy efficiency ratio of the product higher. The condenser adopts the design of vertical shell and tube type, and the copper tube of the evaporator adopts high-efficiency internal thread copper tube, which can effectively improve the thermal effect and is convenient for cleaning.

　　5.The water pump is selected from Italy and Taiwan with large flow and high lift. It is safe, ultra-quiet, power-saving and durable. The shell of the body is painted with electrostatic powder coating, which is beautiful and elegant. Equipped with stainless steel water tank, easy to clean. The water tank contains a floating ball automatic water replenishment device, which can be used to measure and control the water level, thereby effectively saving time and improving work efficiency for customers.
