Detailed Product Description: | Balanced Environment type room calorimeter is the basic unit for measuring the performance of a room air conditioner cooling capacity or main heating capacity, also known as air-conditioning heat balance laboratory, environmental balance calorimeter, room calorimeter and the like. Because room air conditioners using the principles balancing environmental calorimeter, so the usual laboratory room air conditioners are heat balance laboratory. Usually measured as a room air conditioning capability and reference laboratories. Test models: u split air-conditioning; u window air-conditioning. Test items: n standard specifies the name of the performance test conditions; n custom performance test conditions. Test parameters v ability: 3 ~ 12.5kW; v Repeatability: Disposable installed error is less than 1.5%; v primary and secondary deviation 4%; according to the standard: l GB / T 7725 "room air conditioner"; System Principle enthalpy room and program design 2.1 enthalpy room overview Currently, test methods domestic test unit air conditioner is mainly according to GB / T 17758-1999 "unit air conditioner" in Appendix A of the enthalpy difference between the laboratory test methods for the design, Appendix There are five tests prescribed methods: 1, the indoor air enthalpy method; 2, the outdoor air enthalpy method; 3, the compressor calibration method; 4, the refrigerant flow meter method; five outdoor water side of the calorimeter . Test method for testing room air conditioners are mainly in accordance with GB / T 7725-2004 "room air conditioner" in Appendix A of the test method, the appendix provides two methods: 1, room calorimeter method; 2, air enthalpy method. In actual use, the manufacturer of the test in order to take into account the type of air conditioning units, out of the wind patterns, requiring the testing process and other household air testing, air enthalpy method is usually chosen system as the test methods. Mainly air enthalpy method has the following advantages: 1, air enthalpy method can not only static experiments to test the ability of cooling capacity and heating air conditioning and refrigeration products; 2, the air enthalpy method can be performed simultaneously unsteady (dynamic) Performance experiments (including fan performance testing), such as: energy-saving air conditioner season EER (SEER) experiments to be measured intermittently activated cooling capacity and input power commercial air testing / off state of the air conditioner, air conditioner heat pump system defrost Nonsteady process of heating capacity, input power, etc. These non-steady state process must be tested using the air enthalpy method. Time curve, meet the dynamic conditions of the test requirements Hefei enthalpy difference lab | enthalpy difference lab | Hefei days enthalpy test provided by Control Technology Co., Ltd. Hefei day.
