Embodiment Construction

[0033] The simplicity of facility of the present invention is embodied in:

[0034] It only needs a test room (R) and the first temperature measurement point (P) for the indoor average temperature of the temperature sensor, and a matching cooling and heating inverter air conditioner (W) for adjusting the internal temperature of the test room (R), and In order to set the temperature sensing probe to measure the second temperature measuring point (H) of the average temperature of the output cold air or hot air of the air conditioner under test (B), the second temperature measuring point (H) should be set at the air conditioner under test (B) The middle part of the airflow section at the air outlet of cold air or hot air.

[0035] The key equipment in the facility of the present invention is the heating and cooling frequency conversion air conditioner (W), and its first major function is to utilize its cooling and dehumidification working condition, so that the humidity of the ai...

Abstract

The simple refrigerating capacity and heating capacity measuring equipment and method is the improvement and simplification of two patents of the present inventor, ZL01117533.8 and ZL1121361.2. The simple refrigerating capacity and heating capacity measuring equipment consists of mainly one measuring room, the first temperature measuring point for measuring the average temperature in the room and matched frequency varying air conditioner. During refrigerating capacity and heating capacity measurement, the unique parameter to be measured is the input power of the frequency varying air conditioner. The said item may be used freely under arrangement and corresponding technological support may be provided.

Description

Technical field: [0001] The invention relates to thermal testing technology and method thereof. Background technique: [0002] At present, my country's testing of the cooling and heating capacity of room air conditioners is based on "A1: Room-type calorimeter method" and "A2 : Air enthalpy method" two methods to implement. These two methods are direct quantitative testing methods commonly used in the world. They are completely designed to simulate the working environment of the air conditioner on site, especially the influence of the air conditioner on the humidity of the air-conditioned room (the generation of condensed water consumes cooling capacity). Neglected elements are also fully included (although the number is not large), which brings considerable trouble to the test, but in order to ensure the rigor and reliability of the test, as well as the accuracy of the test method, the test facilities have to be High requirements are put forward, so that the price of the as...
