Building exterior wall pre-embedded type heat pipe energy-saving device

Abstract

The invention discloses a building exterior wall pre-embedded type heat pipe energy-saving device, which comprises heat exchange units serially connected and arranged according to flow direction of cycle working medium to form a circulation loop, a power unit for driving the cycle working medium to flow and a buried pipe arranged underground; a working medium compensation unit and a voltage stabilizing unit are further arranged inside the circulation loop; the heat exchange units are pre-embedded inside a building exterior wall, and comprise a summer heat pipe type heat exchanger and a winter heat pipe type heat exchanger arranged in parallel connection and a control unit for selectively turning on one of the summer heat pipe type heat exchanger and the winter heat pipe type heat exchanger. According to the energy-saving device, in summer, the temperature between a building exterior wall painting layer and a masonry base layer can be reduced, the heat transferred to the inner surface of the exterior wall from the outer surface of the exterior wall is reduced, indoor cooling load in summer is reduced; in winter, the temperature between the building exterior wall painting layer and the masonry base layer can be increased, the heat transferred to the inner surface of the exterior wall from the outer surface of the exterior wall is efficiently reduced, indoor heat load in winter is reduced, and indoor energy consumption is reduced.

Description

technical field [0001] The invention belongs to the field of building energy conservation, and in particular relates to a pre-embedded heat pipe energy-saving device on the outer wall of a building. Background technique [0002] Resources, energy and environmental issues are the three major challenges restricting my country's economic and social development. Building energy consumption, including construction energy consumption, living energy consumption, heating and air conditioning energy consumption, etc., is an important part of my country's energy consumption, accounting for about 30% of the total energy consumption of the whole society, of which the most important heating and air conditioning energy consumption accounts for 20%. Therefore, building energy conservation plays a very important role in saving energy, reducing the emission of harmful substances, improving the earth's thermal environment, and achieving sustainable development. At present, the state attaches ...
