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, detects the heat source in the room where the air conditioner is located in real time, and determines the real-time distance between the heat source 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 detect...

Abstract

The invention discloses an air conditioner refrigeration control method and device. The air conditioner refrigeration control method comprises the steps that the real-time indoor environment temperature and the set indoor target temperature are obtained, the temperature difference between the real-time indoor environment temperature and the set indoor target temperature is calculated to serve as the real-time temperature difference, room temperature PID operation is conducted according to the real-time temperature difference, and a first frequency is obtained; the real-time distance between an indoor heat source and an air conditioner is determined and compared with the set distance; if the real-time distance is not smaller than the set distance, an air conditioner compressor is controlled to operate according to the first frequency; and if the real-time distance is smaller than the set distance, the real-time coil temperature of an air conditioner evaporator is obtained, the coil target temperature corresponding to the real-time distance is determined to serve as the real-time coil target temperature, the real-time coil temperature difference between the real-time coil temperature and the real-time coil target temperature is calculated, coil temperature PID operation is conducted, a second frequency is obtained, and the smaller of the first frequency and the second frequency is selected to control the air conditioner compressor to operate. By means of the air conditioner refrigeration control method and device, the good refrigeration comfort can be achieved.

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...
