Calculation method and system for PTC heating power and air conditioner

Abstract

The invention provides a calculation method and system for PTC heating power and an air conditioner. The calculation method for the PTC heating power includes the steps that the current sampling value of at least one performance parameter of the air conditioner is obtained through at least one sampling module; the current sampling values of the performance parameters are input into a software digital model module of the air conditioner; the current PTC heating power of the air conditioner is obtained through calculation according to the current sampling values of the performance parameters and a power calculating digital model preset in the software digital model module. According to the technical scheme, it is unnecessary to add extra hardware cost, the PTC heating power can be calculated accurately just through an existing hardware platform and software modeling means of the air conditioner, then the power consumption of the air conditioner can be obtained accurately, market competitiveness is improved, a user can check the whole conditioner operation condition of the air conditioner in real time conveniently, and therefore the user experience is promoted.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a calculation method of PTC heating power, a calculation system of PTC heating power and an air conditioner. Background technique [0002] At present, applying PTC (PositiveTemperatureCoefficient, positive temperature coefficient, generally referring to semiconductor materials or components with a large positive temperature coefficient) electric auxiliary heating technology to air conditioners can effectively increase the heat generation of air conditioners in heating mode, so , PTC is already a standard device in air conditioners. With the awakening of energy conservation and environmental protection awareness, consumers have become more concerned about the power consumption or operating power of household appliances, and PTC is the most power-consuming part of air conditioners. Devices, if the real-time heating power of the PTC cannot be accurately known, the p...

[0002] At present, applying PTC (PositiveTemperatureCoefficient, positive temperature coefficient, generally referring to semiconductor materials or components with a large positive temperature coefficient) electric auxiliary heating technology to air conditioners can effectively increase the heat generation of air conditioners in heating mode, so , PTC is already a standard device in air conditioners. With the awakening of energy conservation and environmental protection awareness, consumers have become more concerned about the power consumption or operating power of household appliances, and PTC is the most power-consuming part of air conditioners. Devices, if the real-time heating power of the PTC cannot be accurately known, the power consumption of the air conditioner in the heating mode cannot be obtained unless the current sampling link is increased, but this will increase the cost of the air conditioner. In the home appliance industry, increasing costs is not allowed
