Monitoring system suitable for air conditioner

Abstract

The invention discloses a monitoring system suitable for an air conditioner. The monitoring system comprises a plurality of sensor modes, a control main engine, an upper computer, a lower computer, a central air conditioner terminal, a solid voltage regulator and a compressor power measuring module, wherein the sensor nodes are aggregated into an aggregation node which comprises a wireless module 24 L01 and a master control chip STM32F103VET6; the aggregation node and the control main engine realize remote transmission through the Ethernet; a temperature sensor, a humidity sensor, an air quality sensor, a wireless module 24 L01 and an infrared sensing module are arranged on each sensor node; and each infrared sensing module comprises a pyroelectric sensor and an infrared sensing signal processor. The monitoring system disclosed by the invention can be used for performing real-time monitoring on environmental variable parameters such as indoor temperature, humidity and air quality; and output power of a central air conditioner is regulated to be matched with practical load, so that fixed-point fixed-direction regulation according to needs is realized.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a monitoring system suitable for air conditioners. Background technique [0002] At present, due to the lack of advanced technical support, domestic central air-conditioning systems basically adopt the traditional constant flow control method, that is, the air-conditioning chilled water flow, cooling water flow and cooling air volume are all constant. Generally, the central air-conditioning system is designed and selected according to the highest temperature in local history, and a 15-20% margin is reserved. In this way, during normal use, even in the hottest season, the central air conditioning system is not fully operating at full capacity. In the water transfer system of the central air conditioner, the capacity of the chilled water pump and the cooling water pump is also selected according to the maximum design load of the building. As a result, the actual operation situatio...

Problems solved by technology

However, the heat load of the entire building will change dynamically with changes in seasons, day and night, and user needs. The actual heat load of the central air conditioner is far lower than the design load most of the time, and the waste of resources caused by this is also very serious.
