Abstract

An energy saving system utilizing neat accumulation of solar energy phase transition to provide complete heat recovery air is featured as utilizing heat collector of solar energy to convert solar energy to be hot water, utilizing phase transition heat accumulation unit to accumulate solar energy and to change solar energy to be heat energy by using hot water as heat media, utilizing air / water heat exchanger to heat air being completely heat- recovered by complete heat-recovery heat exchanger then sending heated air to air-conditioning room.

Description

technical field [0001] The invention relates to a total heat recovery fresh air energy-saving system using solar energy phase change heat storage, which belongs to the field of air conditioning, heating and ventilation. Background technique [0002] my country is a big country in the construction industry, and the construction industry has become one of the pillar industries of the national economy. Building energy conservation and the sustainable development of the construction industry not only involve the quality of life of ordinary people, but also a major cause related to the national economy and people's livelihood. my country is in a period of rapid urbanization and industrialization, about 2 billion m 2 The total amount of construction is nearly half of the total global annual construction. During this period, my country's new buildings and the original 40 billion m 2 Whether the existing buildings are energy-efficient is not only related to whether the tension in...
