While troubleshooting small-capacity refrigeration systems, a technician should not be too quick to attach refrigerant gauges to a system. Small systems normally hold relatively small amounts of refrigerant. The process of attaching and removing a set of refrigeration gauges will release a small amount of refrigerant from the system.
When installing walk-in coolers and freezers, the installing contractor will need to select the proper location of the condensing unit. Location is an important consideration for the success of the installation. There are several items to consider when selecting the location.
Many field-assembled refrigeration systems require the installing contractor or sales engineer to select the system components. Before any of the system components can be selected, however, the required Btu capacity of the system must be determined.
