detailed description

Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

As shown in Figure 1, it is an intelligent control operation method for a remote-controlled cooling-only air conditioner. The remote-controlled cooling-only air conditioner includes a compressor 1, an outdoor heat exchanger 2, a throttling device 3, an indoor heat exchanger 4, and a control System 5, room air temperature sensor 6, room humidity sensor 7 and outdoor environment temperature sensor 8; said compressor 1, outdoor heat exchanger 2, throttling device 3 and indoor heat exchanger 4 are connected in series; said room air The temperature sensed by the temperature sensor 6 is the room temperature T _n , the humidity sensed by the room air humidity sensor 7 is the relative humidity ф of the room air, and the temperature sensed by the outdoor environment temperature sensor 8 is the outdoor environment temperature T _w , so The control system 5 is electrically connected to the room air temperature sensor 6, the room humidity sensor 7 and the outdoor environment temperature sensor 8 respectively, and the control system 5 controls the operation method steps as follows:

(1) Obtain the functional formula Ⅰ of the cooling capacity Q of the specific type of remote-controlled single-cooling air conditioner changing with the outdoor ambient temperature T _w and the room temperature T _n through experiments or theoretical calculations;

(2) Set the equivalent temperature T _d of thermal comfort, establish the functional formula II of the change of the equivalent temperature T _d with the room temperature T _n and the relative humidity ф of the room air, and use the calculated equivalent temperature T _d as the control The temperature at which system 5 starts and stops is generally based on relative humidity ф=70% as the calculation standard for comfort. Functional formula II can be simplified as: T _d =T _ns +5*(70%-ф), and T in functional formula II _ns is the set room temperature. For example, assuming that the set room temperature T _ns is 26°C, the actual relative humidity ф of the room is 50%, and the equivalent temperature T _d calculated according to the function formula II is 27°C, the air conditioner will use this temperature As the stop temperature of the air conditioner;

(3) Based on the historical temperature meteorological data, establish the general function formula III that the outdoor ambient temperature T _w changes with the time t of the day, and the control system 5 of the air conditioner can receive the weather forecast parameters of the local area and the outdoor temperature detected by the specific air conditioner through the wireless network. Ambient temperature T _w , on the basis of the general function formula III, the specific function formula IV of the outdoor ambient temperature T _w of the specific air conditioner changing with the time t of the day is established; generally, the air conditioner can reach the set room temperature when it is started 1 hour in advance T _ns , in order to make the function formula IV more accurate, it is only necessary to establish a specific function formula within the time period from 1 hour before the set use time to the set use time;

(4) Establish the general functional formula V of the room temperature T _n changing with the outdoor ambient temperature T _w when the air conditioner is not running, and establish the specific functional formula of the indoor temperature T _w of the specific room changing with the time t of the day by detecting the room temperature T _n of the day Ⅵ; Since the change of indoor temperature is related to many factors such as outdoor ambient temperature and room enclosure structure, it is difficult to calculate accurately. The following is a simplified method:

According to the set use time, generally, the air conditioner can reach the set room temperature T _ns when it is started 1 hour ahead of time. Within this 1 hour, the room temperature T _n changes with the outdoor ambient temperature T _w with a fixed temperature difference, that is, the function formula Ⅵ It can be simplified as: T _n =T _w -ΔT. In the function formula VI, ΔT is the temperature difference between the outdoor ambient temperature T _w and the room temperature T _n in the first hour of the set use time, that is, ΔT=T _w -T _n ;

(5) Establish the functional formula VII of the total cooling capacity ΣQ required from the start to the set time t _s , the functional formula VII is related to the actual running time Δt of the air conditioner, the outdoor ambient temperature T _w , and the room temperature T _n , the set indoor temperature T _ns are related to the room envelope structure; in order to simplify the calculation, a general function formula under the standard envelope structure can be established on the basis of the experiment, and then the envelope structure correction coefficient can be introduced for different envelope structures k, that is, the functional formula VII can be expressed as ΣQ=k*f(Δt, T _w , T _n , T _ns ), and the specific k value is obtained from the cooling data of the room where the air conditioner is actually running for 1 to 2 days;

(6) The user inputs the set indoor temperature T _ns and the set time t _s to reach the temperature value, and the control system 5 of the air conditioner is based on the specific function formula IV of the outdoor ambient temperature T _w changing with the time of the day t and the room temperature T _n The specific functional formula VI that changes with the time of the day t, the functional formula I that the cooling capacity Q of the air conditioner changes with the outdoor ambient temperature T _w and the room temperature T _n , the total cooling required during the period from the start to the set time t _s Measure the functional formula VII of ΣQ and the detected outdoor ambient temperature T _w and indoor temperature T _n at that time to determine the early start time of the air conditioner;

(7) When the difference between the room temperature T _n and the set indoor temperature T _ns is -1°C ≤ T _n -T _ns ≤ 1°C, the control system 5 of the air conditioner detects the room temperature T _n and relative humidity ф, according to the function formula II, the actual control temperature of the control system 5 is automatically determined when the control system is turned on and off.

Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the invention is defined by the claims and their equivalents.
