Description

Accurately controlled air conditioner using a remote control

The present invention relates to an air conditioner for precise control using a remote controller, and more particularly, to detect a driving current of a compressor of an outdoor unit to determine a driving state of the compressor, and to determine the indoor temperature by time, daily, weekly, monthly, and season.

It relates to an air conditioner for precise control using a remote control that can save energy by preventing heating and cooling.

In general, an air conditioner heat-exchanges indoor air with a low-temperature gaseous refrigerant during cooling to condense by exchanging heat with a high-temperature, low-pressure gaseous refrigerant heat-exchanged in the indoor unit with outdoor air to release heat. It consists of an outdoor unit. When heating, it takes heat away from the outdoor air as opposed to cooling and heat-exchanges it with the indoor air.

An air conditioner includes a heating device that warms indoor cold air and supplies it to the interior, and a cooling device that supplies indoor air by cooling the hot air.

The value is transmitted to the indoor unit controller 20.

The indoor unit controller 20 receives the compressor operating current value from the outdoor unit controller 30 and determines whether it is "weak operation", "normal operation" or "strong operation" according to the received compressor operation current value.

For example, if it is 500 mA or less, it is determined as "weak operation", if it is 500 mA to 1A, it is determined as "normal operation", and if it is 1A or more, it is determined as "strong operation".

Thus, when the difference between the room temperature detected by the room temperature sensing unit 22 and the indoor set temperature input by the remote controller 100 differs by a threshold value, for example, 3 ° C. or more, the outdoor unit is driven to drive the compressor in a “strong operation”. The command signal is transmitted to the controller 30 to drive the compressor.

In addition, by comparing the indoor set temperature and the room temperature, for example, if the difference is 2 ~ 3 ℃, send a command signal to the outdoor unit controller 30 to drive the compressor in the "normal operation", the indoor set temperature and the room temperature For example, when the difference is less than 1 ° C., a command signal is transmitted to the outdoor unit controller 30 to drive the compressor in “weak operation”.

As such, the compressor driving current is changed according to the difference between the indoor set temperature and the indoor temperature, thereby enabling more precise control.

In addition to the change in the compressor driving current according to the difference between the room set temperature and the room temperature, the air conditioner can be driven by adding the indoor congestion degree.

For example, when the current room is input as "congestion" from the building management system 400, by comparing the room set temperature and the room temperature to control the compressor to operate in "strong operation" even if the difference is less than 3 ℃ If the number of people located indoors to increase the amount of cooling to maintain a more comfortable cooling state.
