Abstract

The invention consists of an environmental and system data acquisition device, pressure, temperature and humidity sensors, a central controller, a data display processor, a remote supervisory and control equipment and a fuzzy controller. The environmental and system data acquisition device includes temperature and humidity gathering devices and it is connected with the three sensors via a shielded cable and also connected with the central controller. The pressure, temperature and humidity sensors are mounted outside the room and each cyclic system of the central controller separately. The central controller is separately connected with the data display processor and the fuzzy controller.

Description

(1) Technical field [0001] The invention relates to a remote monitoring and optimizing energy-saving control device and an energy-saving control method of a central air-conditioning system. (1) Background technology [0002] In the design process of the existing central air-conditioning system, when considering the load capacity of the system, the maximum cooling load (the hottest weather) and the maximum heating load (the coldest weather) of the year are used as the maximum load power to design However, the central air-conditioning auxiliary system cannot dynamically adjust its own operating power according to the outdoor environment temperature and humidity as well as the indoor temperature and humidity, resulting in the central air-conditioning auxiliary equipment always operating at the maximum power of the system design to meet the year-round The objective needs of the coldest and hottest weather in the middle of the year. However, the coldest and hottest time of the y...
