Testing device and method for refrigerating capacity of movable air conditioner

Abstract

The invention provides a testing device and method for the refrigerating capacity of a movable air conditioner. The testing device for the refrigerating capacity of the movable air conditioner comprises an airtight indoor side chamber (1) and an airtight outdoor side chamber (2). The indoor side chamber (1) and the outdoor side chamber (2) are separated through a middle partition wall (3); an air balance hole (4) communicating with the indoor side chamber (1) and the outdoor side chamber (2) is formed in the middle partition wall (3); the size of the air balance hole (4) can be adjusted; the indoor side chamber (1) is used for storing the movable air conditioner; and an air exhaust hole (5) used for exhausting outlet air of the movable air conditioner (6) to the outdoor side chamber (2) is further formed in the middle partition wall (3). The testing device for the refrigerating capacity of the movable air conditioner can test the refrigerating capacity of the movable air conditioner through a heat balance method, and the testing result is accurate and reliable.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning cooling capacity testing, and in particular relates to a mobile air-conditioning cooling capacity testing device and a testing method. Background technique [0002] At present, there are generally two methods for testing the cooling and heating capabilities of air conditioners according to the standard. One is the balanced environment room calorimeter method, and the other is the air enthalpy method. Most types of air conditioners can be tested for cooling and heating capabilities according to the above two test methods, but for mobile air conditioners, the traditional heat balance test method requires that the mobile air conditioner be divided into indoor and outdoor. The structural feature of the mobile air conditioner is that the evaporator and condenser are on the same side, and the air intake is also from the same side. It is impossible to distinguish the inside and outside, so it ca...

Most types of air conditioners can be tested for cooling and heating capabilities according to the above two test methods, but for mobile air conditioners, the traditional heat balance test method requires that the mobile air conditioner be divided into indoor and outdoor. The structural feature of the mobile air conditioner is that the evaporator and condenser are on the same side, and the air intake is also from the same side. It is impossible to distinguish the inside and outside, so it can only be tested in the same test room.

When using the traditional heat balance method to test, the exhaust pipe discharges hot air to the outdoor side, while the indoor room is sealed, which is equivalent to the indoor side being in a "vacuum" state, and the tested mobile air conditioner cannot operate according to the designed circulating air volume, so Cannot be tested by traditional heat balance method
