Yes, it is possible to have more than one refrigerator or cooling unit connected to a single compressor unit. This type of setup is commonly known as a "multi-evaporator" or "shared-compressor" system.
In a multi-evaporator system, a single compressor is used to supply refrigerant to multiple cooling units, each having its own evaporator. The refrigerant flows from the compressor through a network of pipes to each individual evaporator, where it absorbs heat and cools the respective compartments.
This arrangement is commonly found in commercial applications, such as large restaurant kitchens, supermarkets, or cold storage facilities, where there is a need for multiple refrigeration units but the cost and space required for individual compressors in each unit would be impractical.
Having a shared compressor unit can be more energy-efficient and cost-effective, as it reduces the number of compressor units running. It also allows for better temperature control and easier maintenance as you have a centralized unit to monitor and service.
However, it's essential to ensure proper engineering, sizing, and distribution of the refrigerant to each evaporator to maintain optimal performance and efficiency. A well-designed multi-evaporator system should consider factors such as the cooling capacity of each unit, the length and diameter of refrigerant lines, and the overall load distribution among the refrigerators. Professional installation and regular maintenance are crucial to ensuring the system works efficiently and reliably.
