Shulou(Shulou.com)11/24 Report--

According to the news of CTOnews.com8 on March 17, recently, high temperatures have continued all over the country. According to the monitoring and evaluation of the National Climate Center, the comprehensive intensity of regional high temperature events since June 13 this year has reached the strongest since the complete meteorological observation records began in 1961. In this high temperature, many users can not do without air conditioning.

Recently, a picture printed with Gree Logo has aroused public concern about the use of air conditioners at high temperatures. The picture shows that as the temperature will be above 39 ℃ in the coming week, all the air conditioners will reach the critical point of the designed operating range, and then the air conditioners will become worse and worse, and even the outdoor thermal protection will stop.

In this regard, Gree responded that: this is false news, Gree air-conditioning high-temperature performance is good, the current after-sale exposure to non-cooling problems are not many. Therefore, even if the outdoor ground temperature has exceeded 60 ℃, the Gree air conditioner is still in the normal operating range. In addition, a Gree staff member said: "this picture has been around for many years and can no longer be traced back to its source."

It is understood that the normal operating temperature of the air conditioner ranges from-7 ℃ to 43 ℃. In the case of continuous high temperature, the air-conditioning compression machine overheat protection, which is a normal phenomenon caused by the air-conditioning design principle, not the performance of air-conditioning failure. And with the progress of air conditioning refrigeration technology, today's air conditioners can operate normally beyond the above working temperature range.

CTOnews.com learned that air conditioners are composed of compressors, condensers, evaporators, four-way valves and one-way valve capillary assemblies. The principle of refrigeration and heating is the same, all using the endothermic and exothermic phenomena occurred in the phase change process of refrigerants with very low boiling point (such as freon).
