Embodiment Construction

[0029] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] See figure 1 , which is a flow chart of the first embodiment of the air-conditioning and refrigeration control method of the present invention.

[0031] Such as figure 1 As shown, the specific process of the method for realizing air-conditioning refrigeration control in this embodiment is as follows:

[0032] Step 11: The air conditioner operates in cooling mode, obtains the real-time indoor ambient temperature and sets the indoor target temperature; at the same time, obtains the real-time distance between the target in the room where the air conditioner is located and the air conditioner.

[0033] Specifically, when the air conditioner is turned on and running, the indoor ambient temperature of the room where the air conditioner is located is detected in real time, and the real-time detected temper...

Abstract

The invention discloses an air conditioning refrigeration control method and a control device. The method comprises the steps of obtaining the real-time indoor environment temperature and the set indoor target temperature, calculating the temperature difference between the real-time indoor environment temperature and the set indoor target temperature as the real-time temperature difference, and performing room-temperature PID calculation according to the real-time temperature difference, so as to obtain a first frequency; obtaining the real-time distance between an indoor target and an air conditioner, and comparing with the set distance; controlling a compressor of the air conditioner to operate according to the first frequency if the real-time distance is not less than the set distance; obtaining the real-time coil temperature of an evaporator of the air conditioner if the real-time distance is less than the set distance, determining the coil target temperature corresponding to the real-time distance as the real-time coil target temperature, calculating the real-time coil temperature difference between the real-time coil temperature and the real-time coil target temperature, performing coil-temperature PID calculation, so as to obtain a second frequency, and controlling the compressor of the air conditioner to operate by selecting a smaller value from the first frequency and the second frequency. By applying the air conditioning refrigeration control method and the control device, good refrigeration comfortability can be realized.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioning refrigeration control method and a control device. Background technique [0002] In the hot summer, many people cannot do without the air conditioner all day and all night. However, since the outlet air temperature of the air conditioner is much lower than the set temperature, the air outlet temperature of the air conditioner is low, and the blown wind is cold air. When the cold wind blows on the human body, it feels extremely uncomfortable, and it is easy to catch a cold. If you use it for a long time, you are prone to symptoms such as dry mouth, nose, and sore throat, that is, you are prone to air-conditioning diseases. [0003] In order to solve the problem of air-conditioning disease caused by the overcooling of the air outlet temperature of the air conditioner, the existing technology controls the operating frequency of the air condi...
