Product Description

Refrigeration Training System:-

Familiarisation with the layout of refrigeration
· Familiarisation with the main components of
  refrigeration systems
· Measuring relevant temperatures and pressures
· Cyclic process on a p-h state diagram
· Determination of the efficiency
· Determining the coefficient of performance

Technical Description
 The system is designed for the demonstration of the cyclic process on the p-h state diagram. The experimental set-up is clearly laid out on a metal panel. The use of commercially available components ensures a high degree of relevance to practice. A closed hot water circuit with electrical heater is used as a cooling load for the evaporator. The condenser is air-cooled. Electronic sensors provide measured values that are indicated on digital displays. The measured values are also transmitted to a data acquisition card that enables the data to be processed on a PC, e.g. the display of the cyclic process on a p-h state diagram.
