Refrigeration for air conditioning is usually provided by either absorption or compression cycles. Absorption refrigeration uses low-pressure steam or high-temperature hot water as the energy source, water as the refrigerant, and …

The key difference between refrigeration and air conditioning lies in the supply point. The required internal chemicals plus air needed is supplied from the atmosphere. The mechanism is supplied with gas from the pipes. In the case of refrigeration, circulated systems are designed to preserve coolant in a restricted space.

INTRODUCTION This section briefly describes the main features of the refrigeration and air conditioning system. 1.1 What is Refrigeration and Air Conditioning Refrigeration and air conditioning is used to cool products or a building environment. The refrigeration or air conditioning system (R) transfers heat from a cooler low-energy reservoir ...

Heating systems using refrigeration technology are introduced in the chapter. Reversible systems can deliver heating or cooling. Heat can be recovered from various sources, including rejected heat from cooling processes, ground and air. Sources for ground source heat pumps include underground or submerged brine coils.
