| Summary |
In order to clarify the actual in-situ energy efficiency of room air conditioners, the method to evaluate the heating and cooling capacity by measuring refrigerant based on the refrigerant enthalpy method was considered. The refrigerant flow rate and pressures and so on were measured in artificial climate chambers, and an estimation method for refrigerant flow rate were tested. Heating and cooling load calculated by refrigerant flow was compared with heating and cooling load measured by air enthalpy method in the internal unit. |
