Residential gallery air cooling system and operation controlling method thereof

Abstract

The invention discloses a residential gallery air cooling system, which comprises an indoor side and an outdoor side, wherein the outdoor side means a system structure involved in the process of taking cold from the soil by fresh air or mixed air of partial fresh air and return air; the indoor side means a system structure involved in the process of releasing cold indoors by the air treated in a gallery; and the indoor side is connected with the outdoor side to form the circulating gallery air cooling system. The indoor comfortable degree is improved by combining the tail form of displacement ventilation with gallery air cooling. Soil-air heat exchange embedded pipes can be arranged in a building foundation range, so that the initial investment of the system is reduced, the operational efficiency of the system is improved and the application range of the system is enlarged; a condensed water removing and gallery clearing device improves the quality of the indoor air; the invention also provides an operation controlling method for the system; and by the method, the season operation controlling strategy of the gallery air cooling system is optimized, and the energy efficiency coefficient of the system is improved, so that the system is operated in a more reliable and energy-saving mode.

Description

technical field [0001] The invention belongs to the technical field of building ventilation, cooling and energy saving, and specifically relates to a tunnel air cooling system and an operation control method thereof, in particular to a low-investment, high-energy-efficiency cooling system and its operating mode for improving the comfort of residential buildings. Background technique [0002] The tunnel wind cooling technology is a building energy-saving technology that exchanges heat between the air and the soil through buried pipes to achieve the purpose of cooling. On the one hand, the soil is used as a natural cold source to provide cooling for the residence by utilizing the cold storage characteristics of the soil; on the other hand, compared with the traditional air conditioner, the system energy efficiency coefficient (COP) is greatly improved. Based on the characteristics of low investment and high energy efficiency, the application of tunnel air cooling system in the...

AI Technical Summary

Problems solved by technology

A small amount of condensed water is helpful for the heat exchange between the air and the soil, but if it accumulates too much for a long time, bacteria and mildew will easily grow in the tunnel, which will affect the air quality; (2) Tunnel cleaning problems

Open tunnels are easy to attract insects and rats, and long-term use of tunnels tends to accumulate dust and dust, which affects air quality; (3) The location of tunnel buried pipes; The cost of buried pipes; (4) The operation control mode of the tunnel air cooling system
