Field of the Invention The present invention controls an air conditioner (with an air conditioner, an air conditioner, or the like) with a minimum air flow as much as possible, thereby achieving energy saving operation and low noise operation. It relates to the technology to be performed. Conventionally, the amount of circulating air in a room is constant and the flow rate of a chilled water coil and a heating coil in an air conditioner is controlled by a temperature and humidity sensor in the room. In the case of a light load operation in the middle of summer night or in the middle of spring and autumn, the airflow was circulating more than necessary, resulting in large energy loss such as fan power. [0003] This has the following disadvantages. Conventionally, in the case of a clean room that requires 24 hours of operation (such as a bio-clean room in a pharmaceutical factory), a HEPA filter is installed at the outlet of the indoor ceiling, and the fan is operated with a large static pressure of the fan of the air conditioner. The driving power of the motor was high, and the fan noise was also high. In order to control the temperature and humidity in a room (especially temperature), (1) control with the minimum air flow as much as possible, and (2) automatically control the air when it is still not satisfied. Automatically change to temperature control, and (3) perform energy saving operation. (Similarly, the software for automatically changing the air volume control and the air temperature control is also used in the case of remodeling a newly installed device or an existing device.) Embodiments of the present invention will be described below. . This conventional system uses a variable air volume system with an inverter for the blower motor, and automatically changes the air volume control and air temperature control of the air conditioner using D, D, C (digital controller) software. ", The annual running cost such as fan power is greatly reduced. Also, the cold water coil is a direct expansion coil,
By changing the lower limit of the variable air volume range to about 70% of the maximum air volume and replacing the chilled water control valve with an electronic expansion valve, commonly used packaged air conditioners have also been improved to energy-saving air conditioners using fan inverters and "software". It is also possible to further improve the operation control of the fan speed (HI-MID-LO) of the conventional air conditioner by replacing the inverter control with the same control operation program by software. It is also possible. (Both commercial and household air conditioners) This is particularly noticeable for compressor inverter type models. [0006] During the nighttime operation in summer, the operation is performed with a smaller airflow than in the daytime, so that low noise operation is achieved by the inverter. In addition, the life of the HEPA filter is prolonged due to the small air volume operation per year, and the annual running cost of the fan power is greatly reduced.
