Multi-mode independent temperature control method and air conditioner

Abstract

The invention discloses a multi-mode independent temperature control method and an air conditioner. In the invention, temperature control ranges of a user heating mode and a user refrigerating mode are limited respectively. When the indoor temperature is higher than the critical temperature of the refrigerating mode, the refrigerating mode and a corresponding temperature control range are started and used. When the indoor temperature is lower than the critical temperature of the heating mode, the heating mode and a corresponding temperature control range are started and used. The upper limit of the temperature control range of the refrigerating mode, the lower limit of the temperature control range of the heating mode, the critical temperature of the refrigerating mode and the critical temperature of the heating mode can be regulated. The air conditioner comprises an air conditioner body and a control unit, wherein the control unit comprises a main control unit, a temperature mode control unit, a temperature control range reset module, a critical temperature reset module and an indoor temperature sensor. The invention can ensure the air conditioner to always run within a comfortable temperature region, standardizes the air conditioner using habits of the user, satisfies the comfort needs of different populations and has low running cost.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a control method and an air conditioner in which the temperature control ranges of cooling and heating working conditions are independently set, and the upper limit or lower limit of the temperature control range is adjustable. Background technique [0002] The existing air-conditioning cooling and heating modes use the same temperature control range (mostly 18-30°C), and users can set the air-conditioning temperature arbitrarily, resulting in the temperature of the air-conditioning room being too low in summer and the temperature of the air-conditioning room being too high in winter, resulting in Great waste of energy. [0003] In order to solve the above problems, I once proposed a multi-mode temperature control method (application number: 200910310062.1), in which the critical temperature of the cooling and heating modes is set in the air-conditioning system, and the relationship between ...

Problems solved by technology

[0002] The existing air-conditioning cooling and heating modes use the same temperature control range (mostly 18-30°C), and users can set the air-conditioning temperature arbitrarily, resulting in the temperature of the air-conditioning room being too low in summer and the temperature of the air-conditioning room being too high in winter, resulting in huge waste of energy

[0003] In order to solve the above problems, I once proposed a multi-mode temperature control method (application number: 200910310062.1), in which the critical temperature of the cooling and heating modes is set in the air-conditioning system, and the relationship between the ambient temperature and the critical temperature is determined by the air-conditioning system. The system automatically selects the corresponding operating mode. Generally, this method can solve the above problems. However, in extreme weather conditions, it may not be able to operate. The reason is that the ambient temperature detected by the air conditioning system is the outdoor air temperature. If the outdoor temperature suddenly The outdoor air temperature is likely to be lower than the critical temperature, but due to the heat storage effect of the wall, the room temperature is usually relatively high at this time, and the humidity is relatively high, and the air conditioner needs to be operated, but the air conditioner corresponding to the above control method cannot run

[0004] At the same time, the temperature control range of the cooling mode, the temperature control range of the heating mode and the critical temperature in this scheme are all unchanged, which has been greatly improved compared with the previous scheme, and the problem of excessive temperature adjustment is solved. , however, has not addressed the different comfort requirements caused by individual differences

[0005] Therefore, there is a big technical loophole in the above scheme
