Multi-mode control method directly using outdoor cold source and air conditioner

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...

Problems solved by technology

However, the existing air-conditioning refrigeration and heating modes adopt the same temperature control range, and the working mode can be set arbitrarily, without considering the habit of people using air-conditioning, and people of different age groups and different physical conditions have different requirements for the comfort temperature of air-conditioning. Insufficient attention has been paid to this reality, and the temperature adjustment range is too loose, and the air-conditioning temperature can be adjusted arbitrarily, allowing people to form non-standard air-conditioning operation habits, resulting in the situation that the temperature of the air-conditioned room is too low in summer and the temperature of the air-conditioned room is too high in winter

For example, the temperature adjustment range of air conditioners is mostly 18-30°C, but because the adjustable range is too loose, the result is that the air conditioner temperature is set to 18°C ​​in summer and 30°C in winter. The oven is not only far from being comfortable, it may also cause harm to the user's body, causing serious waste of power resources, making the power supply situation in our country even more severe
