Application Introduction In air conditioning processes, often compression chillers are used, in which refrigerants such as R134a circulate, that are ideal as a heat transfer medium due to their thermodynamic properties. In addition, refrigerating-machine oils are in the air conditioning processes to lubricate the compressor. Optimizing compression refrigeration machines, the LiquiSonic® analyzer is used by air-conditioning or compressor manufacturers as well as in research institutes and test bench engineering of various industries. Depending on the design and application of the refrigerator,...

Process The operating principle of compression refrigeration machines is based on a circulating process in which the refrigerant evaporates or expands on one side and absorbs heat from the environment, which leads to a cooling of the corresponding area. On the other side it liquefies and releases heat. The chiller consists of four main components: • • • • expansion valve vaporizer compressor capacitor The expansion valve lowers the high pressure the liquid circulates under. The refrigerant evaporates completely in the evaporator and extracts heat from the environment. In the evaporator, the refrigerant...

The oils serve primarily for lubrication, sealing and cooling of the compressor. Different oil types are used: The oil is located directly in the compressor and circulates inside. It should be separated from the refrigeration circuit through several seals (ring). Due to small leakages, it always comes to an oil entry in the refrigerant. Since in the air-conditioning circuit is a higher pressure, the oil is also partially pushed back into the compressor. This back and forth flow of oil improves the sealing and lubrication of the compressor. Therefore, a small amount of oil is already added within...

Oil concentration measurement Continuous monitoring of the oil content in the refrigerant places high demands on the analysis. On the one hand, there are high pressures, which may be up to 150 bar in case of CO2. On the other hand, the refrigerant is a gas at ambient pressure, which makes manual sampling cumbersome and offline analysis inaccurate. The LiquiSonic® sensors belong to the field of online analytics, measuring continuously and directly in the running process the temperature and pressure compensated oil concentration with an ultra-fast refresh rate. The sensors are installed directly...

LiquiSonic® system LiquiSonic® 30 The LiquiSonic® system consists of one or more sensors and one controller. the electronics housing can be mounted apart from the sensor. The ultrasonic sensor has the actual ultrasonic measuring path and the highly precise temperature detection. For use in hazardous areas, the immersion sensor Ex 40-40 is approved by ATEX and IECEx certification (Ex d IIC T1 to T6 Ga/Gb, zone 0 / zone 1) and FM certification (Class I, Division 1, Groups A, B, C, DT1-T6) The controller 30 is a highly efficient device which includes up to four sensors. They can be installed in...

Sensor The LiquiSonic® sensor is an advanced device designed for continuous and precise inline monitoring of both concentration and temperature in various oil and refrigerant combinations. The parts of the sensor that come into direct contact with the liquid are made from durable stainless steel, ensuring long-lasting performance and reliability. The sensor’s robust and fully enclosed design eliminates the need for gaskets or windows to the process, enhancing its reliability and making it completely maintenance-free, which significantly reduces downtime and operational costs. In addition to its...

Flow adapter Pressure transmitter For an easy integration of the sensor into the process, the flow adapter is ideal and available in various designs. The inlet and outlet are a standard tube with 12 mm diameter (OD), which can be assembled with suitable fittings. In addition, the adapter provides the integration of a pressure sensor. To determine the pressure compensated concentration, the LiquiSonic® analyzer includes a pressure sensor. The pressure is fed and set off by an analog signal of 4 ... 20 mA in the controller. Flow adapter for refrigerant applications Pressure transmitter for refrigerant...
