Optimization of Heat Exchanger Design and Fan

The air-cooled condenser coil is assumed to be a single row, pass, hori­ zontal tube finned heat exchanger. Coil specifications are given in Table 3. The fan consists of a shrouded propeller fan and electric motor in a blow-through arrangement. The Vapor Compression Refrigeration Cycle, Step By StepThe condenser is essentially a heat exchanger. Heat is transferred from the refrigerant to a flow of water. This water goes to a cooling tower for cooling in the case of water-cooled condensation. Note that seawater and air-cooling methods may also play this role. As the refrigerant flows through the condenser, it is in a constant pressure.

What Purpose The Heat Exchanger Use In Refrigeration

Dec 17, 2020 · = 0.0206 m3/s = 20.6 L/s if) The compressor power per kilowatt of refrigeration (which is the reciprocal of the coefficient of performance) is. 10.6 kW. Power of refrigeration =-=0.212 kW/kW. 50 kW (g) The compressor discharge temperature is the temperature of superheated vapor at point 2 which from Fig. A-4 is found to be 57°C. Plate-fin and Tube Heat Exchangers Refrigerant To simulate the vapor compression cycle, a computational package, Genesym v1.0 (Yana Motta, 2001), was employed. It has three modes of operation:heat pump, air conditioning and air-cooled chiller. For the purposes of the present work, it simulated an air-to-air vapor compression cycle air-conditioner operating in steady-state condition.
