Detailed Product Description: | Enthalpy difference laboratory, comprehensive laboratory enthalpy difference, air enthalpy difference lab (certified merchants) are provided by Control Technology Co., Ltd. Hefei days. Hefei days Control Technology Co. (www.testar.com.cn/) is specialized in the "air-conditioning, compressors, refrigeration parts, fans, valves and pumps and other test systems," the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. Huang. Balanced environment type room calorimeter is the basic unit for measuring the performance of a main room air conditioners or heating capacity of refrigeration, air conditioning, also known as thermal equilibrium laboratory, environmental balance calorimeter, such as room calorimeter. Because room air conditioners use a balanced environment calorimeter principle enthalpy difference lab, so the usual laboratory room air conditioners are heat balance laboratory. As is usually the ability to measure the room air conditioning 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 capacity: 3 ~ 12.5kW; v Repeatability: one installed error is less than 1.5%; v primary and secondary deviation 4%; according to the standard: l GB / T 7725 "room air conditioners"; system enthalpy room principle 2.1 Design and 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 test method specified in Appendix five Test method: 1, the indoor air enthalpy method; 2, the outdoor air enthalpy method; 3, the compressor calibration method; 4, the refrigerant flow meter method; 5, outdoor water side calorimeter. Test method to test for room air conditioners are mainly according to 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, the wind pattern, and other requirements of the testing process enthalpy difference lab Which is good, usually choose air enthalpy method system as the test methods. Mainly air enthalpy method has the following advantages: 1, air enthalpy method can not only carry out experiments to test the static cooling capacity and heating capacity of air conditioning and refrigeration products; 2, the air enthalpy method can be performed while the unsteady (dynamic) properties experiments (including fan performance testing) Hefei enthalpy difference laboratory, such as: energy efficiency energy-saving air conditioner season (SEER) of experiments to be measured under intermittent on / off state of the air conditioner's cooling capacity and input power integrated enthalpy difference laboratory, air conditioning Defrost process heat pump heating of Africa steady state heat capacity, input power, etc., these non-steady state process must be tested using the air enthalpy method. Time curve and meet the requirements of dynamic testing conditions |
