Double-glass enclosure system with cooling and shading functions

Abstract

The invention provides a double-glass enclosure system with cooling and shading functions and belongs to the technical field of energy conservation of buildings. The double-glass enclosure system is provided with an inner glass curtain wall and an outer glass curtain wall. An air cavity is formed between the inner glass curtain wall and the outer glass curtain wall. The double-glass enclosure system further comprises multiple cooling water pipes, a cold source, a water pump, a cooling water inlet and a cooling water outlet. The cooling water pipes are arranged in the air cavity in parallel. Each cooling water pipe is provided with a shading blade. The cooling water pipes are connected with the cold source through the cooling water inlet and the cooling water outlet. The water pump is arranged on a pipeline which is located between the cold source and the cooling water outlet or between the cold source and the cooling water inlet. The light transmittance can be flexibly adjusted through a shading blade adjusting mechanism. The cooling water pipes are horizontally or vertically arranged and connected in series or in parallel. By the adoption of the double-glass enclosure system with the cooling and shading functions, heat being conducted to a house through the double-glass enclosure system can be directly eliminated through high-temperature cooling water, and therefore the cooling load of an air conditioner is greatly reduced; the double-glass enclosure system with the cooling and shading functions is simple, easy to use and suitable for popularization.

Description

technical field [0001] The invention relates to a double-layer glass enclosure system, which can directly utilize low-grade natural cooling sources and greatly reduce indoor air-conditioning loads, and belongs to the technical field of building energy conservation. Background technique [0002] In recent years, with the rapid development of my country's economy and the gradual improvement of people's living standards, building energy consumption continues to increase. In 2012, the total energy consumption of buildings in my country reached 690 million tons of standard coal, accounting for about 19.1% of the country's total energy consumption. HVAC accounts for about 2 / 3 of the total energy consumption of buildings, and is undoubtedly the largest energy consumer in buildings. [0003] The summer air-conditioning cooling load of the building is mainly composed of the heat gain of the building envelope and the indoor heat and humidity sources. In the envelope structure, the l...

Problems solved by technology

Therefore, it can only delay and weaken the heat transfer from the outside world, but it cannot really greatly reduce the load of the air conditioner.

Chinese patent literature (CN201420333661.1 and CN201420333382.5) proposes a method of using plants for sunshade between double-layer glass, but the growth of plants is difficult to control artificially, and the light transmittance and angle cannot be flexibly adjusted like sunshade louvers

The Chinese patent document (CN201010100502.3) proposes to embed pipes in the enclosure structure, which can use low-grade energy sources such as soil and cooling towers to directly remove indoor air conditioning loads in summer, but its application objects are mainly walls, not for glass.
