Refrigerating capacity determining method, refrigerating energy efficiency ratio determining method and fault reminding method

Abstract

The invention belongs to the technical field of air conditioners, and particularly relates to a refrigerating capacity determining method, a refrigerating energy efficiency ratio determining method and a fault reminding method for an air conditioner. The refrigerating capacity determining method, the refrigerating energy efficiency ratio determining method and the fault reminding method aim at solving the problem that a refrigerating capacity determining method for the air conditioner in the prior art cannot accurately calculate the refrigerating capacity of an air-cooled air conditioner. Therefrigerating capacity determining method comprises the steps that the indoor air density is obtained; the air supply amount of an indoor unit is obtained; the air inlet enthalpy value of the indoor unit is obtained; the air outlet enthalpy value of the indoor unit is obtained; and the refrigerating capacity of the air conditioner is determined according to the indoor air density, the air supply amount of the indoor unit, the air inlet enthalpy value and the air outlet enthalpy value. According to the refrigerating capacity determining method, the refrigerating energy efficiency ratio determining method and the fault reminding method, the air mass of the indoor unit capable of conducting refrigerating per second is estimated through the indoor air density and the air supply amount, the airinlet enthalpy value and the air outlet enthalpy value can reflect energy contained in air, and therefore the refrigerating capacity can be accurately calculated by combining the indoor air density,the air supply amount, the air inlet enthalpy value and the air outlet enthalpy value.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a method for determining a cooling capacity, a method for determining a cooling energy efficiency ratio, and a method for reminding a failure of an air conditioner. Background technique [0002] With the continuous improvement of people's living standards, people have also put forward higher and higher requirements for the living environment.
