Pumping down and charging
Pumping down and charging Before an engineer can repair a refrigerant leak in the system it has to be located and for this reason leak detection is the first step. If the system has not lost all its refrigerant charge, leak detection may proceed as described in Chapter 3 provided that there is an adequate […]

Refrigerant leak detection
Refrigerant leak detection A leak test is a vital operation after the installation or service of refrigeration equipment. An efficient leak test will prevent expensive call-backs and losses. Shortage of refrigerant in a system results in reduced plant capacity and thus in longer running times of the equipment, which could prove costly to the customer […]

Service valves and gauges
Service valves and gauges System service valves When servicing or commissioning any equipment it is necessary to record the system pressures by fitting pressure gauges. To make this possible, all commercial systems generally include at least three service valves: suction, discharge and liquid shut-off. Suction and discharge service valves may be located on the compressor […]
