Embodiment 1

[0034] An air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle consists of a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to air that has been conditioned and heat exchanged.

[0035] The compressor compresses refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0036] The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve, and returns the refri...

Embodiment 2

[0087] The present invention also proposes an air conditioner, which includes an indoor unit and an outdoor unit. The outdoor unit of the air conditioner refers to the part of the refrigeration cycle that includes the compressor 11 and the outdoor heat exchanger 12. The indoor unit of the air conditioner includes an indoor heat exchanger. 13, and the expansion valve may be provided in an indoor unit or an outdoor unit.

[0088] The indoor heat exchanger 13 and the outdoor heat exchanger 12 function as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in cooling mode.

[0089] The indoor unit is connected to the outdoor unit installed in the outdoor space through a pipe. The outdoor unit may be provided with a compressor 11, an outdoor heat exchanger 12, an outdoor fan 14, an expander an...

Abstract

The invention discloses a fan optimization adjustment method and an air conditioner, and the fan optimization adjustment method comprises the following steps: an outdoor fan optimization adjustment step: detecting the indoor temperature Tair; the difference value between the indoor temperature Tair and the set temperature Tset is judged, and when Tair-Tset is smaller than delta T, the current energy efficiency value COP is calculated; and the COP is compared with the previous energy efficiency value COP ', and when the COP is larger than or equal to the COP', the rotating speed of the outdoor fan is reduced. According to the fan optimizing and adjusting method, the energy efficiency is calculated in real time, on the premise that the indoor temperature requirement is met, the real-time energy efficiency serves as the basis for adjusting the running rotating speed of the fan, the air conditioner fan runs at the optimal rotating speed, and therefore it is guaranteed that the energy efficiency of an air conditioner is optimal.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a fan optimization adjustment method and an air conditioner. Background technique [0002] Air-conditioning products generally have the fan speed set when they leave the factory. The fan speed of the indoor unit is generally determined according to the difference between the indoor temperature and the set temperature, and the fan speed of the outdoor unit is generally determined according to the ambient temperature, so that the temperature of the outdoor heat exchanger can be stabilized within a certain temperature range. [0003] Generally, as the speed of the fan increases, the air volume increases, but at the same time the power consumed increases. For air conditioner heat exchangers, the benefits of increased air volume are not linear. When the air volume is small, increasing the air volume will increase the capacity rapidly, but when the air volume inc...
