As shown in the figure: 1, air-conditioner, 2, first temperature meter, 3, second temperature meter.
The specific embodiment
The control method of automatic balancing room temperature differential is done further explain during to air conditioner heat-production of the present invention below in conjunction with accompanying drawing and specific embodiment.
Like Fig. 1 and shown in Figure 2.
The detected thermometer of temperature sensor is shown the temperature difference that Tr, target temperature be expressed as Ts and upper and lower, room is expressed as δ.Top, described room is meant near the indoor apparatus of air conditioner air inlet that bottom, described room is meant the movable zone of people in the room.Air-conditioner 1 comprises temperature detecting module, room temperature control module and the remote control receiver module of prior art.
Temperature detecting module is used for detecting current indoor temperature Tr, is made up of temperature sensor and reference resistance.What reference resistance adopted is the metalfilmresistor of 5.1K Ω ± 1% precision; What temperature sensor adopted is the thermistor of B value for 3470K ± 1%, R value (25 ℃)=5K Ω ± 1%, can draw Current Temperatures Tr according to resistance of sensor under the corresponding temperature and respective formula.Because detection method is identical with at present general temperature checking method, here just no longer specifies.
The room temperature control module is made up of single chip circuit, and the target temperature Ts that receives according to the detected temperature T r of temperature detecting module and remote control receiver module controls automatically.After remote controller was set and heated, single-chip microcomputer was according to Current Temperatures Tr and target temperature Ts operation, and when target temperature Ts was higher than Current Temperatures Tr, compressor was opened, and after Current Temperatures Tr surpassed target temperature Ts, compressor cut out, and can control room temperature with this.
The remote control receiver module is used to receive the infrared signal that remote controller launches.Comprise information such as switching on and shutting down signal, target temperature Ts, operational mode, indoor set wind speed in the signal.
Air-conditioner is a wall-hanging air conditioner 1 in this specific embodiment, leans on the ceiling place because wall-hanging air conditioner 1 all is mounted in the wall in room, after compressor is opened when heating; Temperature on the air conditioner indoor unit evaporator can rise immediately, and when evaporator temperature reached uniform temperature, indoor fan was opened; Under the guiding of wind-guiding door, hot gas vertically down blows out, and hot gas is because density is little after the evaporimeter that is blown out; All upwards distribute again, the environment temperature of air-conditioner 1 is raise very soon, when the room bulk temperature also under the situation about not rising fully in the room head temperature; The bottom is difficult to experience hot gas, more far feels obvious from air-conditioning, and the upper and lower in room will produce a temperature difference δ like this; Described temperature difference δ draws through the method for experiment measuring, and this temperature difference δ is 3 ℃.
See also shown in Figure 2; Concrete experiment measuring is meant that at area be 15 squares; Height is in 2.8 meters the room, and room wall overhead is equipped with described air-conditioner 1 on 2.5 meters the height, and the people places movable regional optional position one first temperature meter 2 in the room; Place one second temperature meter 3 at the indoor apparatus of air conditioner air inlet, what described first temperature meter and second temperature meter adopted is Fluke 52-II point temperature meter (fluke point is warm to be counted).24 ℃ of starts of remote controller design temperature after air-conditioning heats unlatching, are read a temperature meter temperature displayed and are calculated the temperature difference.After heating 1 minute, 3 to the first temperature meters of second temperature meter, 2 temperature displayed are high 1 ℃; After heating 2 minutes, 3 to the first temperature meters of second temperature meter, 1 temperature displayed is high 2 ℃; After heating 3 minutes, 3 to the first temperature 2 temperature displayed of second temperature meter are high 3 ℃; After heating 10 minutes, 3 to the first temperature meters of second temperature meter, 1 temperature displayed is still high 3 ℃.Second temperature meter 3 temperature displayed reached the temperature that remote controller sets, and at this moment air-conditioner 1 compressor cuts out, and air-conditioning stops to heat.Experimental data shows: the temperature difference of upper and lower, room is 3 ℃, and balance room temperature differential δ can use 3 ℃ by way of compensation, and promptly actual indoor temperature equals the temperature T r that the micro computer in the air-conditioner controller obtains from temperature detecting module and deducts 3 ℃.This experiment measuring all carried out experiment to the room that varies in size, and different according to room-size, the temperature difference δ of upper and lower, described room is 2～3 ℃.
The control method of automatic balancing room temperature differential during air conditioner heat-production of the present invention, concrete control operation pattern is:
1., when Tr-δ＜Ts, air-conditioner 1 compressor is opened, after compressor was opened, room temperature began slowly to rise;
2., when Tr-δ=Ts, air-conditioner 1 continues to keep the state that heats;
3., when Tr-δ＞Ts, air-conditioner 1 compressor cuts out.
See also shown in Figure 1, the control method of automatic balancing room temperature differential during air conditioner heat-production of the present invention, the concrete course of work is: after air-conditioner 1 resets; Infrared remote sensor start (just the remote control receiver module is started working), the user selects heating mode and sets a target temperature Ts with remote controller, and air-conditioner 1 is opened cross valve after receiving signal; At this moment temperature detecting module begins to detect current indoor temperature Tr, and temperature control modules compares Tr-δ and Ts, when Tr-δ＜Ts; Air-conditioner 1 compressor is opened; Compressor heats after opening, and room temperature begins slowly to rise; When Tr-δ=Ts, air-conditioner 1 continues to keep the state that heats; When Tr-δ＞Ts, air-conditioner 1 compressor cuts out, and stops to heat, and when at this moment the remote control receiver module of air-conditioner 1 received the remote controller off signal, air-conditioner 1 was closed cross valve, compressor, stopped to heat, and the process that heats finishes.
