Our process chiller has applications in a number of industrial processes including: injection Moulding and blow moulding, Plastic processing industry, Food Processing industry ,Beverages Industry, Air Conditioning Industry, Water jet Cutting industry, pharmaceutical industries chillers, pipe industries, profile and cast extrusion Industries, vacuum forming industries, Printing industry, Laser & Welding Industry, laminating industry, embossing, calendaring, coating, plating, and high intensity mixers, die casting, die head, wire Cutting, wire coating, and AHU (air handling unit) many more. Since a large portion of our industrial chillers are supplied to the plastics, rubber and process industries, we specialize in their specific process temperature control applications.
HOW THE CHILLER SYSTEM IS WORKING
The basic cooling cycle is the same for both vapour-compression and absorption chillers. Both systems utilize a liquid refrigerant that changes phase to a gas within an evaporator which absorbs heat from the water to be cooled.
The industrial water chillers are the use of water cooling instead of air cooling. In this case the condenser does not cool the hot refrigerant with ambient air, but uses water that is cooled by a cooling tower. Air-cooled chillers actively absorb heat from process water then transfer this heat into the air around the chiller unit. In the process, heat is absorbed from the chilled water circulating through the Condenser. The compressor then pulls the refrigerant vapour from the evaporator.
In Air Cooled chiller return “chilled water” only enters the evaporator where it passes along the outside surface area of the inner tubes, which contain the refrigerant; it then exits at the opposite end having given up its thermal energy. The refrigerant is the only fluid which moves around each of the components of the chiller. It changes its pressure, temperature, enthalpy and entropy as it moves around the machine and transports the unwanted heat away from the evaporator chilled water.
The Air Cooled Chiller has 5 main components.
- THE COMPRESSOR – TYPICALLY SCREW, SCROLL OR RECIPROCATING
- THE CONDENSER – A BUNDLE OF HORIZONTAL PIPES WHICH CONTAIN THE HOT REFRIGERANT, THESE ARE SURROUNDED BY A NUMBER OF THIN SHEETS OF METAL IN THE VERTICAL AXIS. THESE HELP DISTRIBUTE HEAT AWAY FROM THE TUBES AND INTO THE AIR WHICH IS BLOWN ACROSS THE TUBES AND THIN SHEETS OF METAL.
- CONDENSER FANS – THESE SUCK AIR ACROSS THE CONDENSER COILS, ENTERING FROM THE SIDES, AND THEN FORCE THIS AIR OUT THE TOP OF THE UNIT UPWARDS INTO THE AMBIENT ATMOSPHERE.
- EXPANSION VALVE – THIS EXPANDS THE REFRIGERANT BEFORE IT ENTERS THE EVAPORATOR
- EVAPORATOR – THIS IS WHERE THE CHILLED WATER IS PRODUCED AND THE HEAT FROM THE WARM RETURN “CHILLED WATER” IS EXTRACTED, TO BE SENT TO THE CONDENSER.
