Abstract

The invention discloses a PID (Proportion Integration Differentiation) thermostatic adjustment control system for a directly-heated air energy heater, which comprises a control host, a display slave and a valve control execution device, wherein the control host is connected with the display slave by an RS485 (Recommended Standard 485) serial communication interface; the valve control execution device comprises a power drive system, a stepping motor and a valve position detection plate that are sequentially connected by wires; and the control host is connected with the power drive system in the valve control execution device by the wire, and further connected with a data storage unit by a two-wire serial bus. The PID thermostatic adjustment control system for the directly-heated air energy water heater has the advantages that the PID thermostatic adjustment control system is simple in control mode, convenient to mount, and free from season and geographical position influences. Furthermore, the PID thermostatic adjustment control system makes outstanding contributions to energy conservation, environmental protection and the like.

Description

technical field [0001] The invention belongs to the technical field of water heater regulation and control equipment, and relates to a constant temperature regulation and control system of a water heater, in particular to a PID constant temperature regulation and control system of a direct heating air energy water heater. Background technique [0002] In recent years in China, the air energy water heater industry has developed rapidly. With the continuous rise of "low-carbon economy" in 2010, the air energy industry has ushered in a new opportunity for development. As far as the overall situation is concerned, opportunities and challenges coexist. With the gradual escalation of advertising wars, price wars, and technical wars in the air energy industry, it has become the development direction of air energy companies to pay close attention to technological innovation, master core technologies, and take a professional route. [0003] With the continuous acceleration of global ...
