The range of Chillers for Hire at All Seasons Hire is extensive starting at 5kW through to 750kW. The latest 750kW chillers to arrive in the hire fleet are manufactured exclusively for All Seasons Hire; they use 8 Copeland Scroll compressors using r410a refrigerant.
Vapour compression cycle refrigerants are those which change their physical state from liquid to vapour and back again, during the refrigeration cycle. The phase change is used to “collect” heat from the evaporator and transfer heat to the condenser. Refrigerants which change their phase at the required temperature only exist as vapours at normal ambient […]
Refrigerant is one of the key components in a refrigeration system and should be selected with great care because its choice can impact, substantially, on the system design, and ancillary mechanical components. The refrigerant should be selected to ensure that the system will be cost effective (throughout the lifetime operation of the system and should […]
Vapor absorption cycle In the early years of the twentieth century, the vapor absorption cycle using water-ammonia systems was popular and widely used but, after the development of the vapor compression cycle, it lost much of its importance because of its low coefficient of performance (about one fifth of that of the vapor compression cycle). Nowadays, the […]
Vapor-compression cycle The vapor-compression cycle is used in most household refrigerators as well as in many large commercial and industrial refrigeration systems. Figure 1 provides a schematic diagram of the components of a typical vapor-compression refrigeration system. Figure 1: Vapor compression refrigeration The thermodynamics of the cycle can be analyzed on a diagram as shown in Figure 2. […]
