Floor radiant cool-supplying air-feeding system based on thermal comfort

Abstract

The invention provides a floor radiant cool-supplying air-feeding system based on thermal comfort. The air-feeding system comprises a radiant cool-supplying system, a floor air-feeding system and a thermal comfort detection control system. The floor radiant cool-supplying air-feeding system based on the thermal comfort has the beneficial effects that most of the cooling capacity required for cool-supplying of the air-feeding system comes from the cooling liquids stored inside a radiant coil pipe, an air conditioning unit only needs to auxiliarily provide 10-20% of the cooling capacity, the cooling source in the radiant coil pipe can come from some natural cooling sources to feed air evenly, and compared with a traditional floor air-feeding system which performs cool-supplying through the air conditioning unit, the energy consumption can be reduced by 20-40%. According to the floor radiant cool-supplying air-feeding system based on the thermal comfort, under the control of a control main center, ultraviolet ray sterilamps are turned on for half an hour every week to sterilize the space of the radiant coil pipe; the system performs real time monitoring on the temperature, humidity, black ball temperature, air speed and all other parameters of indoor personnel activity area, thus a real-time PMV value is calculated, comparison with a preset value is performed, and under the adjusting and control of the control main center, the indoor personnel are kept in a thermal comfort environment; and by means of the floor radiant cool-supplying air-feeding system based on the thermal comfort, the thermal comfort requirements of the personnel in a room are met utilizing the radiant cool-supplying method, and the floor radiant cool-supplying air-feeding system based on the thermal comfort conforms to the concept of energy conservation and sustainable development.

Description

technical field [0001] The invention belongs to the technical field of building indoor ventilation and air conditioning, and focuses on the technical field of building floor air supply, in particular to a floor radiation cooling and air supply system based on thermal comfort. Background technique [0002] With the development of economy and technology, the floor air supply system has been widely used, and the floor air supply system needs to be continuously improved to meet the needs of contemporary people. The air supply speed of the floor air supply system currently used is uneven, the required cooling capacity is provided by the air conditioning unit, and the required fresh air volume must be provided by a dedicated fresh air system, resulting in high energy consumption of the air conditioning unit. Contents of the invention [0003] In view of the structural deficiencies in the prior art, the purpose of the present invention is to provide a floor radiation cooling and ...
