Air conditioner refrigerating capacity and heating capacity testing method and air pipe box heat meter

Abstract

The invention relates to an air conditioner refrigerating capacity and heating capacity testing method and an air pipe box heat meter applicable to the method. The air pipe box heat meter comprises an air pipe box, a freezing water system and a measurement control device, wherein the freezing water system comprises a freezing water coiled pipe arranged in the air pipe box; and the air pipe box is internally provided with a heating device, a humidifying device and a draught fan. The measurement method comprises the following steps that after an air conditioner starts and is led into an air pipe box; and the measurement control device controls work states of the freezing water system, the heating device, the humidifying device and the draught fan so that a dry ball temperature and a wet ball temperature of air which flows out of the air pipe box are the same as a dry ball temperature and a wet ball temperature of air which flows into an air inlet of the air conditioner to be measured; and therefore, the refrigerating capacity and the heating capacity of the air conditioner to be measured are calculated. According to the air conditioner refrigerating capacity and heating capacity testing method and the air pipe box heat meter applicable to the method, the problems that the existing method can not independently measure the refrigerating capacity and the heating capacity of the air conditioner and can not be used as an auxiliary testing method of an enthalpy potential method, and the manufacturing cost of needed equipment is high are solved.

Description

technical field [0001] The invention relates to a method for testing the cooling capacity and heating capacity of an air conditioner and an air duct box calorimeter suitable for the method. Background technique [0002] In my country's national standard GB / T7725-2004 "Room Air Conditioners", it is recommended to use the room calorimeter method and the enthalpy difference method to test the cooling and heating capacity of air conditioners; in the international standard ISO5151-2010 "Non-ducted air conditions and heat pumps-Testing and rating for performance" (Chinese is the performance test and rating of air conditioners without ducts and heat pumps), it is proposed to use the room calorimeter method and the enthalpy difference method to test the cooling capacity and heating capacity of the air conditioner. It is also recommended that when using the indoor enthalpy difference method for measurement, the following methods can be selected as auxiliary measurement methods: ...

Problems solved by technology

[0011] The invention provides a method for measuring the cooling capacity and heating capacity of an air conditioner that can independently measure the cooling capacity and heating capacity of the air conditioner and can also be used as an auxiliary measurement method for the indoor enthalpy difference method, and the required equipment manufacturing cost is relatively low, and realizes the method. The air duct box calorimeter of the method solves the problem that the existing air conditioner cooling capacity and heating capacity measurement method cannot not only independently measure the cooling capacity and heating capacity of the air conditioner, but also be used as an auxiliary measurement method for the indoor enthalpy difference method. The problem of high production cost of the required equipment
