本文指出习惯上常用的房间空调器(以下简称空调器)制冷量的定义:Q=G(Ⅰ_1-Ⅰ_2)是不精确的,它与空调器制冷量的真实值Q_0间存在着恒定误差.并进一步论证了空调器制冷量的正确定义应为Q_0=G(Ⅰ_1-Ⅰ_2)-Wi_(w(_2)).指出焓差法或风管热平衡法空调器制冷量的测定是以定义Q=G(Ⅰ_1-Ⅰ_2)为依据的,前者的误差不小于3%,后者不小于0.6%,而房间热平衡法空调器制冷量的测定装置的设计是符合正确定义的,根据房间热平衡法空调器制冷量测试标准的规定,它的单次测定结果的误差不大于0.5%,多次测定结果的平均值将更接近于真实值.
This paper points out that the commonly used definition of room air conditioner (hereinafter referred to as air conditioner): Q = G (I_1 - Ⅰ_2) is imprecise, and it has a constant error with the actual value of air conditioner cooling capacity Q_0 It is further demonstrated that the correct definition of the air conditioner cooling capacity should be Q_0 = G (Ⅰ_1-Ⅰ_2) -Wi_ (w (_2)). It is pointed out that the enthalpy difference method or duct heat balance air conditioner cooling capacity is determined by the definition of Q = G (Ⅰ_1-Ⅰ_2), the error of the former is not less than 3% and the latter is not less than 0.6%. The design of the device for measuring the cooling capacity of the room air-conditioner air conditioner is in accordance with the correct definition. According to the air-conditioner cooling method The amount of test standards, the error of a single determination of its results is not more than 0.5%, the average of multiple determinations will be closer to the true value.
