At this condition, it is an optimum condition for cooling cop but it is not the highest cooling capacity. Recover refrigerant to increase the suction superheat. Superheat charging chart how to find target superheat and actual superheat on an air conditioner youtube in 2020 hvac hvac services hvac tools. The evaporator manufacturer should have designed the evaporator to provide the required cooling capacity at a specific superheat. Other areas of study for learning how to properly charge an air conditioner or heat pump would be boyles law. Heating and air conditioning image by how to check a txv for proper work. The evaporator superheat method should be the first effective method of properly charging a fixed refrigerant metering system. Check valves that are sticking open or closed are a common problem for heat pumps. The fact that these readings are normal indicates the low suction pressure is. We will again find a heat exchanger in this unit along with a fan, a reversing valve, check valve and an expansion the refrigerant leaves the compressor as a high pressure, high temperature superheated vapor.
Total superheat = suction line temperature (at watch both superheat and subcooling when refrigerant charging and troubleshooting. Having the correct superheat at the evaporator is important.
