Split System Heat Pump – Compressor. 

The function is to create and maintain the low pressure in the evaporator that allows the evaporation of the coolant is at low temperature. Moreover creates and maintains the high pressure in the condenser that allows reuse of liquid refrigerant. The refrigerant in the compressor is at low pressure and temperature during suction and high pressure and temperature in the discharge. Steam compressors used in industrial refrigeration or air conditioning are of three main types: reciprocating, rotary and centrifugal. 

Ductless Air Conditioning – Evaporator. 

The evaporator is any heat transfer surface in which a volatile liquid is vaporized to remove heat from a space or chilled product. Due to the different applications evaporators are manufactured in a variety of types, shapes, sizes and designs. The evaporators are usually constructed of steel or copper tube. 

Split System HVAC – Condenser. 

Is a heat transfer surface. The heat of the hot refrigerant vapor passes through the walls of the condenser for condensation. As a result of heat loss to the environment condensing,  the refrigerant vapor is first cooled to saturation and then condensed to its liquid state phase. Capacitors are generally three types: air cooled, water cooled evaporators employing both air and water. 

Split System Heating and Cooling – Expansion Device (valve). 

This device is responsible for spraying or expand the refrigerant. Their role is twofold, firstly regulates the amount of liquid entering the evaporator so that, depending on the amount of fumes sucked in by the compressor, can be maintained constant evaporator pressure.
