400-816-6687Air conditioning enthalpy difference method laboratory
1. Overview:
This test room uses the air enthalpy difference method to measure the cooling capacity, heating capacity, low-temperature non-steady-state heating capacity, power consumption, C.O.P., circulation air volume and seasonal energy consumption efficiency of room air conditioners. It can be used as an important means of detection equipment and design and development of room air conditioners. The test room conditions meet the requirements of standards GB/T 7725-2004 and JIS B 8615-1.
This test room includes two rooms (indoor and outdoor), each of which is equipped with an air handling unit to control the air state in each room. In addition, the indoor side contains a set of air volume measurement devices for measuring the air volume and outlet enthalpy of the machine under test. The air volume measurement device includes a static pressure box, a receiving room, a nozzle and an induced draft fan.
The measurement method is to install the air conditioner under test in the actual way, and by controlling the dry-bulb and wet-bulb temperatures on the indoor and outdoor sides of the machine under test, measure the temperature, humidity and air volume of the inlet and outlet air of the indoor unit, so as to calculate the cooling and heating capacity.
This laboratory can be expanded into a one-to-three enthalpy difference laboratory (consisting of four constant temperature chambers), which can carry out tests on one set of one-to-three air conditioners, or independently and simultaneously carry out tests on two sets of one-to-one air conditioners.
