Control method and device for improving heating speed of air conditioner

Abstract

The invention provides a control method and device for improving heating speed of an air conditioner. The method comprises the following steps of: collecting the temperature of an indoor coil pipe when the air conditioner is at a standby state and an outdoor air temperature is less than or equal to a first outdoor temperature and an indoor temperature is less than or equal to the first indoor temperature; preheating the indoor coil pipe when the indoor coil pipe temperature is less than the first set temperature: starting up a compressor for preheating the indoor coil pipe, and stopping the compressor until the indoor coil pipe temperature is greater than or equal to a first set temperature, and delaying to stop an outdoor fan; and preheating the indoor coil pipe repeatedly when the indoor coil pipe temperature is less than a second set temperature. The control device comprises a starting module, a determination module and a preheating module, wherein the determination module is used for comparing the indoor coil pipe temperature and the preset temperature; and the preheating module controls the starting and stopping of the compressor according to the determined result so as to preheat the indoor coil pipe repeatedly. According to the invention, the heating speed of the air conditioner can be improved, and the effect that heating can be carried out once the air conditioner is started up is realized.

Description

technical field [0001] The invention relates to a control method and a control device for increasing the heating speed of an air conditioner. Background technique [0002] Many air conditioning systems do not work well when heating in winter, and it takes a long time to blow out comfortable hot air. The heating speed is slow, and the heating effect cannot satisfy the user. [0003] For example, Chinese invention patent publication No. 201593848 discloses an air conditioner with a heating device, which is composed of an air conditioner and a heating body assembly, and the heating body assembly is installed on the air inlet side or the air outlet side of the indoor part of the air conditioner. In the prior art, the disadvantage is that the air conditioner cannot be preheated, and hot air cannot be directly blown out after starting the heating mode. [0004] As another example, the Chinese Utility Model Publication No. 201032312 discloses a high-efficiency and quick-heating t...
