Product feature
Air-cooled chillers achieve cooling through a vapor compression refrigeration cycle, primarily comprising three interconnected systems:
● Refrigerant Circulation System: Liquid refrigerant absorbs heat and evaporates in the evaporator, forming gaseous refrigerant. This gaseous refrigerant is compressed by the compressor to a high-temperature, high-pressure state, then enters the condenser where a fan dissipates heat into the air, causing it to condense back into liquid refrigerant. The liquid refrigerant then passes through an expansion valve, becoming a low-temperature, low-pressure refrigerant, which enters the evaporator to continue absorbing heat, completing the cycle.
● Water Circulation System: A water pump draws water from the tank and pumps it to the equipment requiring cooling. After removing heat, the water's temperature rises, and it returns to the tank. A float switch in the tank controls the water level and temperature.
● Electrical Control System: This includes the power supply and automatic control components. The power supply provides power to the compressor, fan, and water pump via contactors. The automatic control system includes a thermostat, pressure protection, timer, relays, and overload protection, automatically starting and stopping the system based on water temperature.
