Supermarket refrigeration systems account for over half of all energy consumption in supermarkets, making them one of the most energy-intensive types of equipment in the commercial construction sector.
Furthermore, the multiplex direct expansion (DX) system, which is prone to refrigerant leaks because of its extensive lengths of refrigerant piping, is the most often utilized refrigeration system in supermarket applications. This leakage diminishes the system’s efficiency and raises the system’s environmental effect.
Due to the high Global Warming Potential (GWP) of the hydrofluorocarbon (HFC) refrigerants usually employed in these systems, as well as the huge refrigerant charge and high refrigerant leakage rates, significant direct emissions of greenhouse gases into the environment are produced.
Properties of Refrigerants Used in Commercial Refrigeration System
Here are some important properties that a refrigerant must have:
Extremely High Critical Pressure
The refrigerant’s critical pressure should be higher than the condenser pressures. Otherwise, the condensation zone shrinks and heat rejection occurs.
Vapor Density: Extremely High
Smaller compressors are required for refrigerants with a high vapor density/low specific volume, and velocity can be kept low, allowing for smaller condenser tubes to be employed.
Dielectric strength Should Be High
Short circuits can occur when refrigerant vapor contacts motor windings in hermetically sealed compressors. To avoid short circuits, the dielectric strength should be strong.
Low Freezing Point
The freezing point of refrigerants should be lower than the regular working conditions. During the application, it should not freeze. Water, for instance, cannot be utilized below 0 degrees Celsius.
Condensing Pressure Is Low
The lower the condenser pressure, the less compression power is required. High operating costs will result from increased condenser pressure. Low-boiling-point refrigerants have a high vapor density and condenser pressure. The condenser tubes must be built for higher pressures, which increases the equipment’s capital cost.
