Abstract

The invention discloses an air conditioner which comprises a calculating unit used for calculating the indoor temperature difference delta T between the indoor environment temperature and the indoor set temperature, and a control unit, configured to, when the air conditioner starts to refrigerate and operates at the target superheat degree, control and adjust the superheat degree according to thedelta T and the current superheat degree at set intervals; when the air conditioner starts to heat and operates at the target liquid pipe temperature, control and adjust the liquid pipe temperature according to the delta T and the current liquid pipe temperature at set intervals; and when the air conditioner conducts refrigeration and the delta T is smaller than the low-temperature set value for afirst time period or when the air conditioner conducts heating and the delta T is larger than the high-temperature set value for a second time period, control an indoor unit to stop. The air conditioner is used for solving the problems of frequent starting and stopping and low air outlet comfort after the indoor unit reaches the set temperature, frequent starting and stopping are avoided, the energy consumption ratio is reduced, the service life of the compressor is prolonged, and the user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner. Background technique [0002] The technology of multi-connected air source heat pumps is becoming more and more mature, and it is widely used in household and commercial fields. The multi-connected air source heat pump includes at least one indoor unit and at least one outdoor unit module connected to each indoor unit through a refrigerant connection pipeline. When there are two or more indoor units, each indoor unit is arranged side by side and each indoor unit It has an indoor heat exchanger and a corresponding indoor fan. When there are two or more outdoor unit modules, each outdoor unit module is arranged side by side and each outdoor unit module has a compressor, a four-way valve, a Flow elements, outdoor heat exchangers and outdoor fans. [0003] Most of the existing multi-split units of manufacturers often operate at the maximum c...
