Intelligent frequency conversion temperature difference control system

Abstract

The invention discloses an intelligent frequency conversion temperature difference control system, and relates to the technical field of heating. The problems that too large or too small temperature difference exists between supplied water and returned water, imbalance of a heat supply system is caused, previously, a circular water pump works in a full load manner all the time, the service life ofthe water pump is quite easily shortened, and the electric energy consumption amount is large are solved. According to the temperature difference generated between secondary side water supply and return pipes, according to the magnitude of the temperature difference, data processing is carried out through a software control system to achieve frequency conversion control over the circular water pump, the circular flow speed of the secondary side is changed, and the heat supply imbalance generated by a secondary side water supply and return system is adjusted. The intelligent frequency conversion temperature difference control system comprises temperature sensors which are arranged on the secondary side water supply and return pipes, a temperature sensing line, an intelligent frequency conversion temperature difference controller, a frequency conversion output control line, and a frequency conversion water pump. The system is mostly used for heating and domestic hot water systems.

Description

technical field [0001] The present invention is an intelligent frequency conversion temperature difference control system, specifically, it is a control and adjustment of heat in the secondary side circulation system of HVAC heat exchange equipment. During the control and adjustment process, energy saving and intelligence can be achieved. The system can replace the adjustment function of the temperature control valve, occupies less space for the heat exchange system equipment, and can also provide an appearance decoration for the heat exchange equipment, so as to achieve strong safety and practicality in HVAC technology, energy saving, Economical, beautiful, small space occupation, etc., the invention relates to the secondary side intelligent frequency conversion temperature difference control system of the heating and domestic water heat exchange system. Background technique [0002] At present, there are various types of heat exchange systems. Basically, plate heat exchang...

Problems solved by technology

[0002] At present, there are various types of heat exchange systems. Basically, plate heat exchange and volumetric heat exchange are used for heat exchange and hot water supply. However, the control equipment on the heat exchange system is bulky, expensive, and has a short service life. , will also increase the local resistance in the circulatory system, greatly increasing the kinetic energy loss of the circulatory system. With the scarcity of social resources, energy-saving heating systems and reducing the equipment cost of heat exchange systems have become issues of concern to people from all walks of life. The emergence of an intelligent variable frequency temperature difference control system is urgent
