Abstract
A control method for an air conditioner which can perform low-temperature refrigeration is characterized in that an external fan is shut down to reduce heat exchange when that an indoor coil pipe is lower than a temperature value T<1> for a time duration t<1> is detected and a compressor operates continuously for more than t<y1>; the compressor is shut down and an internal fan operates according to a preset wind speed to perform anti-freezing protection when the indoor coil pipe is lower than a preset temperature value T<2> for a time duration t<2> and the compressor operates continuously for more than t<y2>; the whole set returns to normal operation when the indoor coil pipe is higher than a temperature value T<3>, and the external fan and the compressor are started, so that the air conditioner can refrigerate normally at a low temperature. The inventive method is simple and no other hardware is needed. The air conditioner can be started at a low temperature without basically changing indoor heat exchange effect and low-temperature refrigeration ability.
Description
Technical field
The present invention relates to a kind of air-conditioner control method, especially relate to the air-conditioner control method of energy cryogenic refrigeration.
Background technology
The tradition air-conditioning can only can normally move more than 10 ℃ in environment temperature, and running refrigerating below 10 ℃ will use the large-area frosting of indoor evaporator or freeze, even have the phenomenon of evaporimeter copper pipe because of the explosion of freezing, not only also there is safe problem in poor refrigerating efficiency.And the specific (special) requirements in part country or special area, 20 ℃-30 ℃ of indoor temperatures, outdoor 5 ℃--5 ℃ of requirements can normally be freezed, and there are the problems referred to above certainly in traditional air-conditioning running refrigerating under so abominable operating mode.
A kind of cold-starting method is disclosed though the patent No. is China's " patent start-up method of air-conditioner in low temperature circumstance " of 200510015944.7, comprise air-conditioner work certain hour after, the indoor and outdoor temperature sensor carries out the 1st stage of perception to the pipe arrangement temperature; As the indoor tube temperature of the 1st stage perception less than the 1st temperature, outdoor piping temperature less than the 2nd temperature, the 2nd stage then the rotating speed of outdoor unit fan of air conditioner is controlled less than the speed of setting rotating speed; As the outdoor machine fan rotating speed less than minimum a reference value, indoor tube temperature less than the 3rd temperature, then stop the 3rd stage of outdoor machine fan and compressor operating; Through behind the certain hour, start both the 4th stages more respectively.The present invention according to the rotating speed of the outdoor machine fan of its adjustment, even the indoor tube temperature is in low-temperature condition, also can start compressor by perception air-conditioner indoor tube temperature and outdoor piping temperature.It need carry out parameter control according to indoor tube temperature and outdoor piping temperature and outdoor unit fan of air conditioner rotating speed, realizes cold-starting, and detected parameters is many, and control method is easy inadequately.
Summary of the invention
Technical problem to be solved by this invention provide a kind of easier, need not other hardware, indoor heat exchange effect is constant substantially, the cryogenic refrigeration ability is constant substantially can cryogenic refrigeration air-conditioner control method.
It is such that the present invention solves the problems of the technologies described above the technical scheme that is adopted: the air-conditioner control method of a kind of energy cryogenic refrigeration, and it is characterized in that utilizing the indoor coil pipe sensor to detect the function of coil temperature, detect indoor coil and be lower than certain temperature value T

Wind speed setting refers to the wind speed that the user sets with remote controller: high wind speed (1180r/min), middle wind speed (1050r/min), low wind speed (900r/min).
Compared with prior art, the invention has the advantages that: the air-conditioning of this cryogenic refrigeration function can reach following effect, 20 ℃-30 ℃ of indoor temperatures, and outdoor 5 ℃--under 5 ℃ the working condition,
Evaporator surface frosting maximum area: the facing the wind frost area of surface condensation of evaporimeter, should not descend greater than 50% or air quantity of evaporimeter front face area be no more than 25% of initial air quantity;
The ability of cryogenic refrigeration: the actual measurement refrigerating capacity of air-conditioner should be less than 90% of specified refrigerating capacity; The time of frequent start-stop: be not more than 40% of total run time the downtime of compressor;
And method is easier easily, and is safe and reliable, need not other hardware, just can realize by software.
The specific embodiment
Below in conjunction with embodiment the present invention is described in further detail.
The air-conditioner control method of a kind of energy cryogenic refrigeration utilizes indoor coil sensor such as thermistor to detect the function of coil temperature, detects indoor coil and is lower than certain temperature value T
