Chillers use either a vapor-compression or absorption refrigerant cycle to cool a fluid for heat transfer. Both chiller types rely on three basic principles.

    The diaphragm reacts to the system and regulates the pressure differential across the actuated control valve orifice to maintain its flow rate. HVAC Controls Electric Actuators Electric Heaters “Air conditioning” is defined as the conditioning of indoor air in order to maintain its temperature, humidity, cleanli- ness and air movement at levels suited to human health and

    heating and cooling systems turn on - a gap of around 4 to 5ºC between the heating and cooling thermostat set points will create a comfortable ‘dead band’. 17/06/2012 · Water chillers are backbone of HVAC cooling systems.Water chiller is a refrigeration machine which produces chilled water ( Approx 7 Degree C ~ 12 Degree C).The primary function of a chiller is to lower the temperature of water to such value such that it can be used for producing cooling effect in integration with other HVAC components.
