A heating and cooling system that couples an additional sunlight room and a double-layer rotating phase-change wall

Abstract

The invention discloses a heating and cooling system for coupling an additional sunlight room and a double-layer rotating phase-change wall, comprising a rotating glass (2) and a rotating double-layer phase-change wall (3), the rotating glass (2) adopts two The two-layer glass curtain wall (7) is respectively fixed on both sides of the rotating glass keel (8); The change layer (15) and the second phase change layer (16) are respectively attached to areas other than the vents (131), (132), (133) and (134) on both sides of the double-layer wallboard (11). The invention only consumes the power consumption of wall rotation and fan operation, and can use the phase change layer of the rotating wall to fully store cold and heat, thereby reducing the building's cooling and heating load, and realizing low-cost cooling and heating; , so that the outside cold air enters the room for heat exchange, without rotating the wall; it can avoid the heat dissipation from the outside of the wall to the room due to the rotation of the wall.

Description

technical field [0001] The invention relates to the heating and cooling technology used in the fields of green buildings and renewable energy, in particular to a heating and cooling system coupled with an additional sunlight room and double-layer rotating phase-change walls. Background technique [0002] At present, China's total building energy consumption is 899 million tons of standard coal, accounting for 20.6% of the country's total energy consumption; the country's total building area is 63.5 billion square meters, and the urban per capita residential building area is 34.9 square meters; the total building carbon emissions are 19.6 million tons of CO 2 , accounting for 19.4% of the country's total energy carbon emissions. Therefore, it is necessary to adopt high technology to reduce building energy consumption and reduce building carbon emissions. [0003] Phase change material (PCM) refers to the functional material that absorbs or releases a large amount of latent ...

Problems solved by technology

However, this invention has the following problems: 1. Whether it is summer or winter, the rotating wall rotates the phase change layer to the outside, passively stores cold and heat, and lacks measures to strengthen heat exchange, resulting in the cold or heat stored per unit time Relatively little, can not maximize the use of natural cooling or heat

Especially in severe cold weather in winter, when the outdoor temperature is low, only relying on passive heat storage, it is difficult for the phase change layer to store enough heat during the day

2. The rotating wall only lays a phase-change layer on the outside of the wall, but a single-layer phase-change wall can generally only reduce building energy consumption and improve room thermal comfort in a certain season, and its applicability is relatively large throughout the year. Difference

If the wall is rotated at night so that the outside of the high-temperature wall becomes the inside of the wall, the outside of the wall may dissipate heat to the room and increase the cooling load
