Embodiment Construction
[0025] The present invention will be further described below in conjunction with accompanying drawing.
[0026] A device for SEER measurement based on a common enthalpy difference chamber, see attached figure 2 , including ordinary enthalpy difference chambers, said ordinary enthalpy difference chambers are outdoor 1, indoor 2, control room 4, stabilized power supply 8, indoor working condition unit 12, outdoor working condition unit 14, in the control room 4 The electric control cabinet 7 and the test computer 5, the air volume measuring device 11 on the indoor side, the frequency conversion fan 9, and the connecting hose 10. Two sets of identical units were installed in the enthalpy difference chamber, of which one set A was the air conditioner unit to be tested, and the other set B was a stable unit under intermittent conditions. The outdoor units 13 and 16 of A and B machines are all placed on the outdoor side 1 of the enthalpy difference chamber, and the indoor units 3 ...

The invention provides a device and a method for performing SEER measurement based on a common enthalpy-difference chamber. The device comprises the common enthalpy-difference chamber and two sets of identical air conditioner units arranged in the enthalpy-difference chamber for achieving the aim of the invention, wherein one set of the air conditioner unit is a tested air conditioner unit, while the other set is a stable unit with discontinuous working condition. An indoor set of the tested air conditioner unit is connected with an air-quantity measuring device through an air outlet pipe, an air outlet thermocouple grating and a return air thermocouple grating are arranged on the air outlet side and the return air side of the indoor set respectively, and a control device is used for realizing the starting and the stopping of the two sets of the air conditioner units and a frequency-changing fan. The device and the method can perform a discontinuous refrigeration test in the common enthalpy-difference chamber; and data of the discontinuous refrigeration air outlet and the return air temperature obtained by the thermocouple gratings and data of stable state B and C working condition tests are convenient to calculate the SEER. The technical proposal has less investment and is easy to carry out.
Description
technical field [0001] The invention belongs to the field of refrigeration and air conditioning, in particular to a device and method for measuring SEER based on a common enthalpy difference chamber. Background technique [0002] Common air-conditioning enthalpy difference chambers owned by domestic air-conditioning manufacturers are attached figure 1 , which includes an outdoor side 1, an indoor side 2, a control room 4, a stabilized power supply 8, an indoor working unit 12, an outdoor working unit 14, and an electric control cabinet 7 and a test computer 5 in the control room 4. During capacity testing, the outdoor unit 13 of the air conditioner is placed on the outdoor side 1 of the enthalpy difference chamber, the indoor unit is placed on the indoor side 2, the indoor and outdoor units are connected through an intermediate connecting pipe, and the indoor unit is connected to the air volume measuring device through the air outlet pipe 6 11 is connected, and the connecti...
