Abstract

The invention provides a multi-mode control method directly using an outdoor cold source and an air conditioner. The air conditioner has the basic functions of the existing air conditioner, and additionally, a new fan control module (6) and a temperature control mode selecting module (9) are arranged in a main control chip; a machine set is additionally provided with a new fan / port (5), an indoor temperature sensor (7) and an outdoor temperature sensor (8); comfortable temperature regulating range of refrigeration and heating operation modes is automatically selected according to the set refrigeration and heating mode critical temperatures, and the air conditioner of the upper limit value of refrigeration working condition temperature control range and the lower limit value of heating working condition is adjustable so as to meet the special comfort level requirement caused by individual difference; and two functions of 'common fresh air' and 'energy-saving fresh air' are added. The control method and the air conditioner not only can improve the quality of indoor air and utilize the outdoor cold source at right time, but also can cultivate the comfortable and energy-saving operation habit of the air conditioner, save the operation cost and energy consumption of the air conditioner and have great economic significance and application value.

Description

technical field

[0001] The invention provides a multi-mode control method and an air conditioner that directly utilizes an outdoor cold source, specifically, a new type of energy-saving air conditioner that directly utilizes outdoor low-temperature air. Background technique

[0002] Due to the heat storage effect of the building wall, even if there is no indoor heat source, the natural temperature drop rate of the indoor temperature at night in summer is much slower than that of the outdoor temperature. Therefore, during a certain period of time at night, the outdoor temperature is lower than the indoor temperature. It is a good solution to draw the outdoor low-temperature air directly into the room and use the outdoor cold source to reduce the energy consumption of the air conditioner.

[0003] At present, in order to occupy market share and pursue profits, air-conditioning companies are more and more inclined to meet the individual requirements of users on the basis of rea...
