Phase change fresh air pipeline system based on sky radiation and solar heat collection

Abstract

The invention discloses a phase change fresh air pipeline system based on sky radiation and solar heat collection. A phase change pipe section is installed on an air inlet pipeline of a fresh air handling unit, a surface air cooler is installed in the fresh air handling unit, and a fresh air machine is installed on an air supply pipeline of the fresh air handling unit. A water outlet pipe of the phase change pipe section communicates with the inlet pipe ends of a solar heat collector and a sky radiation cooler, the outlet pipe ends of the solar heat collector and the sky radiation cooler communicate with the water outlet pipe of the phase change pipe section, and a circulating working medium pump is installed on the water outlet pipe. The phase change fresh air pipeline system has the beneficial effects that by arranging a phase change working medium formed by shaping a phase change material is arranged in the phase change pipe section, a heat-carrying circulating working medium of a capillary circulating pipe substitutes heat or cold into a shaping phase-change working medium, and the shaping phase change working medium can conduct corresponding phase change cold storage or heat storage. Through heat dissipation of the phase change pipe section and heat exchange with flowing fresh air, cold is supplied to the fresh air flowing through the phase change pipe section all day long in summer, heat is supplied to the fresh air flowing through the phase change pipe section all day long in winter, and energy conservation and environment protection are achieved.

Description

Technical field [0001] The present invention relates to the use of EEB and technical field of renewable energy, in particular a sky radiation and solar collectors based on a phase change fresh air piping system. Background technique [0002] In recent years, with the continuous improvement of living standards, people are increasingly high indoor air quality architectural requirements, which increased the demand for fresh air. After the usual air system is using a fan to outdoor air through the fresh air is piped into the fresh air unit cooler, heat exchange with the coil in the chilled water or hot water, and then sent to the indoor, the process will consume a lot of cold or heat to the outdoor air to deal with indoor air state, especially in low winter temperatures in summer and outdoor high outdoor temperatures. New wind load as the main source of building heating and air-conditioning load, which greatly increase the energy consumption of the building heating and air conditioni...

AI Technical Summary

Problems solved by technology

In view of the above technical background, the fresh air system has the characteristics of wide application range, high energy consumption, and lack of energy-saving measures, which cannot fully meet the needs of building energy conservation and consumption reduction
