The circuit consists of four main components: the evaporator, the condenser, the compressor, and the expansion device. Industries & Topics Refrigerant circuit In the evaporator, the refrigerant absorbs heat and evaporates. The gaseous refrigerant is then compressed in the compressor, causing the pressure and temperature to rise. In the condenser, the hot refrigerant releases the absorbed heat and liquefies. The refrigerant expands through the expansion valve, the pressure drops, and the process begins anew. Testing the refrigerant circuit Several factors must be taken into account during the commissioning and testing of the refrigerant circuit. First, the tightness of all connections and components must be verified to help prevent loss of refrigerant. The correct refrigerant charge is crucial for efficient operation. Electrical connections, especially at the compressor and the control unit, must be professionally installed. The pressure and temperature values should be checked in accordance with the manufacturer's specifications. A functional test ensures that all components operate properly during operation. Finally, it is important to carefully document all tests and settings. Step by step instructions and automatic documentation The new AFRISO digital manifold gauge guides the user step by step through all complex measurements on the refrigerant circuit. It clearly shows the measuring points to be checked, provides notes on correct execution, and assists in evaluating the measurement results. In the process, all relevant values, such as pressure or temperature, are systematically prompted and documented. This ensures that no important inspection steps are overlooked and that commissioning and testing are carried out in and efficiently and reliable way.
