Study of refrigeration and air condition unit lab report

Heat is given up to the cooling water and the refrigerant condenses to liquid before passing to the expansion valve. Closed cycle vapor compression heat pumps electric and engine driven ii. Refrigerator consists of four main components which are; compressor, evaporator, expansion valve and condenser.

The process cycle of heat pump is clearly illustrated in pressure enthalpy diagram. Experiment 3 The experiment is to determine the production of vapor compression cycle on p-h diagram nd energy balance study The experiment is to study determine the production of heat pump perfomance curves over a range of evaporating and condensation temperature.

Thus, as it flows through the evaporator, there is a temperature difference between the refrigerant and the water being drawn across the coils. Areas of interest include heating of buildings, recovery of industrial waste heat for steam production and heating of process water for e. The pressure of the circulating substance working fluid is reduced back to the evaporator condition in the throttling valve.

The objectives of this experiment is to determine the power input, heat output and coefficient of perfomance. Thus, the temperature rises and the hot vapor then enters the water cooled condenser.

This experiment demonstrated the general operation of vapor compression heat pump. Experiment 5 The objectives of this experiment is to estimate the effect of compressor pressure ratio on volumetric efficiency.

The heat pump consists of a hermetic compressor, a water-cooled plate heat exchanger, a thermostatic expansion valve and a water heated plate heat exchanger. The objectives of this experiment is to determine the production of heat pump perfomance curves over a range of source and delivery temperatures.

This causes the saturation temperature to fell to below that the atmospheric. Heat transformers a type of absorption heat pump iii. A refrigeration unit is a unit composed of several machineries that can transfer heat from a low-temperature region to a high-temperature region.

In the evaporator the heat is extracted from the heat source to boil the circulating substance ii. Each component works together to perform a series of process. The objectives of this experiment successfully achieved.

Vapor compression heat pump cycle The components are; 1. Generally, there are three types of heat pump systems: The process includes a cycle of refrigerant and a flow of cooling water. The temperature at which heat is delivered in the condenser and the evaporator is controlled by the water flow rate and its inlet temperature.

Heat pump technology has attracted increasing attention as one of the most promising technologies to save energy.

During the operation, slightly superheated refrigerant Ra vapor enters the compressor from the evaporator and its pressure is increased.

The resulting heat transfer causes the refrigerant to boil, and upon leaving the evaporator it has become slightly superheated vapor, ready to return to the compressor. Instrumentations are all provided for the measurement of flow rates of both refrigerant and cooling water, power input to the compressor and all relevant temperatures.Avail the fantastic range of Refrigeration & Air Conditioning Lab Manufacturers, Supplier and Exporter.
