The following are the main parts of electrical system of a domestic refrigerator: 1. Compressor motor 2. Starting relay 3. Thermostat 4. Thermal overload protector or release. A brief description of each part, along with its function, is as below: 1. Compressor Motor: It may be a DC motor. Since we have mostly AC supply so AC motor is used [...]
In this article we will discuss about the working of refrigeration cycle with the help of a diagram. In order for lowering the temperature of a body below that of its surroundings and then maintain it, a continuous extraction of the heat from the body is required. This is done by a mechanism called the refrigeration system. The total amount [...]
There are two refrigeration systems: 1. Vapour Compression Refrigeration System 2. Vapour Absorption Refrigeration System. 1. Vapour Compression Refrigeration System: This is the most important system for commercial and domestic utility. The working fluid, known as refrigerant. It can be used over a large range of temperatures. Working: The working substance (refrigerant) is such that it readily evaporates and condenses. [...]
Window air conditioner consists of a compressor, a condenser, a drier, filter, capillary tube and an evaporator, An electric motor drive the fan to circulate air through condenser coil and runs a blower to deliver either cool air to room or suck air from it before forcing through the evaporator coil which cools as well as dehumidifies the air. A [...]
