1.1 Objectives
The basic objectives of this experiment are to understand the HVAC system and vapor compression cycle system through the experimental accomplishment.
Therefore, the main objectives of this experiment are as follows:
1) To understand the difference between the theoretical single-stage compression cycle and the real one.
2) To investigate the performance of the refrigeration systems, the efficiency of the compressors and the cooling coefficient of performance.
3) To investigate the effect of the fan speed on the performance of the refrigeration systems through the experiments for the control of the fan speed in the heat exchanger of the condenser and the evaporator.
4) To investigate the things of number 2) and 3) through the P-h diagram
5) To study the characteristics of R-22 which is used in this experiment and general importance for refrigerants.
1.2 Theory
Refrigeration is the transfer of energy from a space, or air supplied to a space, by virtue.
