Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] The invention provides a constant temperature and dehumidification control method for a heat pump air conditioner, such as figure 1 As shown, first set the first comparison threshold ΔT, and when performing constant temperature dehumidification, firstly, continuously detect the current ambient temperature Tr, and compare it with the user’s set temperature Ts in real time to determine whether the current ambient temperature Tr is higher or lower than the user’s Whether the temperature Ts is set and the difference Ts-Tr between the two exceeds the first comparison threshold ΔT is used to determine whether the cooling or heating device is used first, and then the constant temperature dehumidification device is started to perform constant temperature dehumidification. If it is detected that the current ambient temperature Tr is higher than the temperature Ts set b...

Abstract

The invention discloses a constant temperature dehumidification control method and a device for a heat pump type air conditioner, and the method comprises the following steps: setting a first comparison threshold, constantly detecting the current environmental temperature, obtaining the judgment result of whether to start a refrigerating device or a heating device firstly according to the situation that whether the current environmental temperature is higher than or lower than the temperature set by a user and exceeds the first comparison threshold or not, and then re-starting the constant temperature dehumidification device; if the current environmental temperature is higher than the temperature set by the user and exceeds the first comparison threshold, the refrigerating device is firstly started for refrigerating; if the current environmental temperature is lower than the temperature set by the user and exceeds the first comparison threshold, the electric heating device is firstly started for heating; otherwise, the constant temperature dehumidification device is directly started. The method and the device can decide whether to start the refrigerating device or the heating device firstly through the comparison of the current environmental temperature with the temperature set by the user, thereby realizing constant temperature dehumidification of the air conditioner and solving the problem of discomfort of the user caused by reducing the indoor temperature during the dehumidification process.

Description

technical field [0001] The invention relates to a heat pump air conditioner, in particular to a constant temperature and dehumidification control method and device for the heat pump air conditioner. Background technique [0002] With the rapid development of the national economy and the continuous improvement of people's living standards, people have higher and higher requirements for the comfort of living and working environments, and not only the temperature but also the humidity are also required to be controlled and adjusted. [0003] Nowadays, household air conditioners usually have the functions of cooling, heating, and dehumidification. However, during the dehumidification operation, the indoor heat exchanger will be in a low-temperature state. Feel out of place. In order to solve this contradiction, the dehumidification function of existing air conditioners is generally designed to operate with low wind and intermittent operation. However, this dehumidification meth...
