Embodiment Construction

[0013] The air conditioning system applicable to the present invention can be two independent units, one unit is responsible for producing water at the temperature required for heating and cooling at the radiation end, and the other unit is responsible for producing fresh air with suitable temperature and humidity required indoors; it can also be a The radiant fresh air integrated unit, under cooling conditions, first prepares lower temperature water to prepare fresh air with suitable temperature and humidity for the room, and then passes through the intermediate heat exchanger to obtain higher temperature water required for radiant end cooling. Under the heating condition, the higher temperature water is first produced to be responsible for the fresh air with suitable temperature and humidity required in the room, and then through the intermediate heat exchanger to obtain the lower temperature water required for the heating of the radiant end.

Abstract

The invention discloses a central air-conditioning control system combining radiation terminal cooling and warming and fresh air. The central air-conditioning control system comprises a controller, a man-machine interactive interface, an analog quantity input module, an analog quantity output module, a switching value control module, a water pump frequency converter, an air-feeding fan frequency converter, an air-returning fan frequency converter, a water-inlet temperature sensor, a water-outlet temperature sensor, an indoor temperature sensor, an indoor humidity sensor and an indoor carbon dioxide concentration sensor. The central air-conditioning control system is simple and reliable, effectively meets the requirements of indoor persons on temperature, humidity and fresh air quality, and realizes energy-saving operation.

Description

technical field [0001] The invention relates to a central air-conditioning system with heating and cooling at the radiant end and fresh air, in particular to a household control method for a new air-conditioning system with heating and cooling at the radiant end and fresh air. Background technique [0002] With the development of the economy and the improvement of people's living standards, people's requirements for air-conditioning comfort and indoor air quality have also increased; at the same time, the energy consumption of air-conditioning in buildings is also increasing. The air-conditioning system with radiant terminal cooling and heating combined with fresh air treatment is considered to be an economical, energy-saving and comfortable form of central air-conditioning system, and has been gradually studied and applied. Radiant end heating refers to changing the temperature of the ceiling, wall or floor in the enclosure structure to form a radiation surface, relying on ...
