Internet of things heating and air conditioning energy-saving water-saving control system

Abstract

An Internet of things control system for heating and energy and water saving of air conditioning comprises an terminal intelligent control part (1), a heating and air conditioning host energy and water saving control center (2), a central air conditioning system host (5), an air conditioning host controller (6), a water pump (10), a fan (11), at least two frequency converters (9), a total return water pipe temperature sensor (7), a total water outlet pipe temperature sensor (8) and a water supply branch pipe electric control valve (12). The terminal intelligent control part (1), the air conditioning host controller (6) and the heating and air conditioning host energy saving control center (2) are two-way connected. The air conditioning host controller (6) is connected with the central air conditioning system host (5). The heating and air conditioning host energy and water saving control center (2) is connected with the water pump (10) and the fan (11) through different frequency converters (9). The total return water pipe temperature sensor and the total water outlet pipe temperature sensor (8) are both connected with the heating and air conditioning host energy and water saving control center (2).

Description

technical field [0001] The invention relates to an energy-saving and water-saving control system for heating and air conditioning of the Internet of Things. Background technique [0002] The working conditions of existing heating boilers, central air-conditioning system hosts, system water pump fans and other equipment are not strongly related to the end load, thus causing a great waste of energy in the central heating system and central air-conditioning system. In order to solve this disadvantage, people generally adjust the combustion intensity of the heating boiler, the working status of the main engine of the central air conditioning system, the system The frequency conversion of the water pump fan, however, has the disadvantages of slow response speed, waste of energy and water resources in this way of relying on temperature regulation. [0003] Chinese patent 200720122432.5 discloses a central air-conditioning variable temperature difference energy saving control syst...
