Reverse Cycle Refrigeration And Air Con Training Unit

Product Description

Description of Reverse Cycle Refrigeration and Air Con Training UnitReverse Cycle Refrigeration and Air Con Training Unit unit demonstrates both refrigeration and air conditioning principles as well as operation of two evaporators on one compressor by means of an evaporator pressure regulator. The hermetic condensing Reverse Cycle Refrigeration and Air Con Training Unit has a high starting torque motor with built-in winding protector, air-cooled condenser and liquid receiver. A water cooled condenser is provided with an automatic condenser pressure regulator. Both the forced air evaporator and the static evaporator has a 3/8 O.D. copper tube coil block with aluminium fins. The Flow Controls may be selected by hand valves. These comprise: Automatic expansion valve; internal equalised thermostatic expansion valve; External equalised thermostatic expansion valve. and Capillary tube with separate filter drier.Specification of Reverse Cycle Refrigeration and Air Con Training UnitThe unit is mounted in a steel frame with stainless steel base and back panels and incorporates: -Hermetic Condensing Unit: Having a high starting torque motor with built-in winding protector, air-cooled condenser and liquid receiver Remote Water-cooled Condenser Forced Air Evaporator: Coil block: 3/8 O.D. copper tube with aluminium fins Flow Controls: Automatic expansion valve.
