Abstract
The invention discloses a control method of a multi-split air conditioner, which comprises the steps of: primarily detecting indoor temperature through an indoor temperature sensor, judging whether the indoor temperature is higher than the set temperature, if so, stopping operating an indoor machine, and if not, operating the indoor machine; and after the indoor machine stops operating, the control method comprises the steps of: secondarily detecting the indoor temperature through the indoor temperature sensor, and judging whether the indoor temperature detected secondarily is higher than the first temperature, if so, controlling a fan to intermittently operate, and if not, closing the fan. Through controlling the operation mode of the fan under different conditions, the purpose of reducing the accuracy of the temperature sensor by an evaporator can be achieved, and the effect of saving energy is obtained.
Description
Technical field
The present invention relates to the air-conditioner field, particularly relate to a kind of control method of multi-split air conditioner.
Background technology
Multi-split air conditioner is meant the air-conditioner of many indoor set runnings of an off-premises station band.During multi-split air conditioner work, when more than one indoor set moved simultaneously, if one of them indoor set reaches design temperature, machine should stop.Design methods existing is: the evaporimeter of indoor set is provided with temperature sensor, is used to gather indoor temperature, when indoor when reaching design temperature, and the indoor set that stops.But because the temperature of evaporimeter is very high, the temperature of evaporimeter is easy to have influence on the temperature accuracy that temperature sensor is gathered, for example, indoor actual temperature is 25 ℃, and the temperature of evaporimeter may reach about 40 ℃, even it is higher, so the temperature that temperature sensor is gathered may be 30 ℃, for fear of the influence of evaporimeter to temperature sensor, needs fan to move with gentle breeze always, but can cause energy loss with the gentle breeze operation, be unfavorable for energy-conservation.
Summary of the invention
The purpose of this invention is to provide a kind ofly, promptly can reach and reduce evaporimeter, have the control method of a kind of multi-split air conditioner of energy-saving effect again the accurate sex purpose of temperature sensor at multi-split air conditioner.
For achieving the above object, technical scheme of the present invention provides a kind of control method of multi-split air conditioner, and described method comprises:
Detect indoor temperature for the first time by indoor temperature transmitter, and whether judge described indoor temperature greater than design temperature, if then indoor set is out of service, if not, then indoor set operation,
After indoor set is out of service, further comprising the steps of:
Detect indoor temperature for the second time by indoor temperature transmitter, and judge that whether the indoor temperature that detects for the second time is greater than first temperature, if then control the fan intermittent operation; If not, then close fan.
Wherein, when the fan intermittent operation, further comprising the steps of:
Detect indoor temperature for the third time by indoor temperature transmitter, and judge whether the indoor temperature that detects for the third time is lower than second temperature, if, then close fan, if not, then continue control fan intermittent operation.
Wherein, during described fan intermittent operation, the time of fan running is less than the fan time intermittently.
Wherein, the time of described fan running is 3 minutes; The described fan time intermittently is 7 minutes.
Wherein, described first temperature is 14 ℃.
Wherein, described second temperature is 16 ℃.
Technique scheme has following advantage: by under different situations the fan running form being controlled, promptly can reach and reduce evaporimeter to the accurate sex purpose of temperature sensor, have energy-saving effect again.
Description of drawings
Fig. 1 is the flow chart of control method of a kind of multi-split air conditioner of the embodiment of the invention.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention.
The air-conditioner control method of present embodiment is applicable to multi-split air conditioner, as shown in Figure 1, at first detect indoor temperature by temperature sensor, and judge that whether indoor temperature is greater than design temperature, as long as when having one not reach design temperature in a plurality of indoor sets, carry out Energy Saving Control by the following method:
Detect indoor temperature for the second time by indoor temperature transmitter, and judge that whether the indoor temperature that detects for the second time is greater than first temperature, if then control the fan intermittent operation; If not, then close fan, fan is shut down.
When the fan intermittent operation, further comprising the steps of: as to detect indoor temperature for the third time by indoor temperature transmitter, and judge whether the indoor temperature that detects for the third time is lower than second temperature, if, then close fan, fan is shut down, if then control the fan intermittent operation.
Wherein, during the fan intermittent operation, the time of fan running is less than the fan time intermittently.Preferred scheme is that fan running 3 minutes stops 7 minutes.First temperature, second temperature can be provided with according to the environment for use of air-conditioner, and different environments for use can be different, and the preferred scheme of present embodiment is, first temperature is 14 ℃, and second temperature is 16 ℃.
Describe with instantiation below: when multi-split air conditioner is worked, temperature sensor on wherein any indoor set detects indoor temperature, if indoor temperature is higher than 16 ℃ (comprise and equaling), then control the fan intermittent operation, be specially fan running 3 minutes, stop 7 minutes, cycle operation successively, if indoor temperature is lower than 16 ℃, then close the fan of wind to temperature sensor, it is shut down.When fan with intermittent operation after a period of time, temperature sensor detects indoor temperature once more, if this moment, indoor temperature was higher than 14 ℃, continues control fan intermittent operation, is specially fan running 3 minutes, stops 7 minutes, successively cycle operation; If when the detected once more indoor temperature of temperature sensor is lower than 14 ℃ (comprise and equaling), then close the fan of wind, be that it shuts down to temperature sensor.
As can be seen from the above embodiments, the embodiment of the invention has promptly reached the purpose to the temperature sensor heat radiation by under different situations the fan running form being controlled, and has energy-conservation effect again.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
