Embodiment Construction

[0031] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0032] Such as figure 1 As shown, in the dehumidification control method of this embodiment, the microprocessor M37546 collects the indoor coil temperature TE and the indoor ambient temperature TA, and compares the above information with the air conditioner set temperature TS or specific values. At the same time, the microprocessor M37546 monitors the operating conditions of the compressor, outdoor fan, indoor fan, and PCT electric heater and controls their operating modes.

[0033] Such as figure 2 As shown, in the dehumidification control method of this embodiment, there are three control modes. After the air conditioner starts, the microprocessor M37546 first performs the following judgment operations:

[0034] Step 1: Does the air condit...

Abstract

A dehumidification controlling method for an air conditioner with a PTC (positive temperature coefficient) electrical heater includes steps of acquiring the indoor coil temperature TE and the indoor environmental temperature TA when the air conditioner runs in a dehumidifying mode, comparing the indoor coil temperature TA to the indoor environmental temperature TA; monitoring running conditions of a compressor, an outdoor fan, an indoor fan and the PTC electrical heater; and controlling running modes of the compressor, the outdoor fan, the indoor fan and the PTC electric heater. The PTC electrical heater is turned on or turned off properly during dehumidification, so that the heat loss caused by dehumidification can be recovered by the electrical heater and the dehumidification at a constant temperature can be achieved.

Description

technical field [0001] The invention relates to a dehumidification control method for an air conditioner with a PCT electric heater, belonging to the field of indoor air conditioning. Background technique [0002] Air with high humidity not only makes people feel stuffy and uncomfortable, but also causes serious corrosion to buildings and decorations. [0003] When the air conditioner is in cooling operation, the indoor air meets the extremely low temperature evaporator and condenses into water droplets. This is the dehumidification principle of the existing air conditioner. Therefore, in order to achieve the purpose of dehumidification in the existing air conditioners, that is, when operating in the dehumidification mode, the indoor temperature will inevitably drop, which makes it difficult to meet the requirements of constant temperature dehumidification in situations such as tea storage. [0004] PTC (Positive Temperature Coefficient, referred to as PTC, positive tempera...
