Description

Environment adaptive air conditioning system and method

The present invention relates to an air conditioning technology that can save energy by operating in accordance with the environmental conditions such as temperature, humidity, weather, climate according to seasonal date and time.

Air conditioning refers to adjusting the temperature, humidity, ventilation, cleanliness, etc. of the air to an optimal state according to the purpose of use for a human or an article in an indoor space. The most common use of such air conditioning equipment is air conditioning for cooling and heating purposes.

First, the heating method, there is an individual heating method for generating heat by installing a furnace, a heater, etc. directly in the room, and a central heating method for supplying fruit (熱 媒) made by a boiler or the like through a pipe. Here, the central heating includes direct heating for placing a radiator in the room and indirect heating for supplying warm air.

On the other hand, in the case of cooling, including a compressor, a condenser, an expansion valve, and an evaporator, the refrigerant is compressed in the compressor and then condensed in the condenser to release heat to the outside, and again the refrigerant passes through the expansion valve and then vaporizes in the evaporator. After absorbing the refrigeration cycle is supplied to the compressor again cooling is made. At this time, the outdoor unit serves to discharge the heat radiated from the condenser to the outside, the evaporator is provided in the air conditioner of the room that requires cooling to absorb the heat of the room.

In addition, in the case of a conventional air conditioner, a boiler for heating and a cooler for cooling are separately provided to take a structure in which heating and cooling equipment are mixed. In recent years, the use of a heat pump type air conditioner to simultaneously perform heating and cooling as one facility is increasing. The heat pump circulates the refrigerant according to the normal refrigeration cycle during the cooling operation, and the circulation of the refrigerant is reversed during the heating operation so that the outdoor unit absorbs heat and discharges the heat from the air conditioner. It is a device to perform and heating at the same time. In a heat pump type air conditioner, a 4-way valve for controlling the circulation of the refrigerant is generally used. In some cases, the condensation heat radiated from the condenser forming the cooling cycle is recovered and used for heating or hot water supply.

On the other hand, air conditioners are also provided to reduce the power consumption of the compressor by applying a voltage reduced by a predetermined magnitude than a commercial AC power source in accordance with the change in the room temperature to adjust the drive speed of the compressor.

However, the compressor consumes 85% of the power consumed by the air conditioner, and the compressor continues to operate until the indoor temperature detected by the temperature sensor becomes lower than the set temperature input by the user from the time when the operation is started. do. Therefore, it is inconvenient for the user to set an appropriate temperature, and furthermore, the air conditioning equipment can save energy by operating in accordance with the environmental conditions such as humidity, weather and climate as well as temperature according to the date and time of each season. There is a need for air conditioning technology.
