Description

Heat pipe implanted intelligent heat exchange wall

technical field

The invention belongs to buildings, in particular to a heat pipe implanted intelligent heat exchange wall. the

Background technique

Low-energy buildings refer to energy-saving buildings whose energy consumption indicators are lower than the current standards, and this type of buildings will become the development trend of buildings in the future. my country's building energy consumption accounts for 27.8% of the total energy consumption, of which more than one-third is used for heating and cooling of buildings. Low-energy buildings refer to the use of renewable energy for heating and cooling of buildings without or as little primary energy as possible. Low-energy buildings have high thermal insulation requirements for the external wall envelope, and high-efficiency external thermal insulation systems are usually used. For example, the external wall insulation technology of polyurethane composite rubber powder polystyrene particles and the external wall insulation technology of polystyrene boards pasted with rubber powder polystyrene particles can carry out all the external facades of the building, all the overhanging components of the external walls and the attached wall parts. Insulation treatment, cut off all thermal bridges. Low-energy buildings adopt ground-based low-temperature heating/cooling systems, and the radiant temperature of cold and heat is close to or equal to the upper and lower limits of the indoor comfortable temperature, making people feel very comfortable. The application of solar heat collection technology to the heating system can further save energy consumption for heating in winter. Due to the excellent heat insulation performance of the envelope structure of low-energy buildings, the cooling and heating load of the building envelope is relatively low, and the thermal environment system suitable for low-energy buildings is one of the key technologies for the large-scale promotion of low-energy buildings. the

work process:

Winter Implementation Plan

Heat exchange tubes are installed on the inner and outer surfaces of the south wall of the low-energy building. The height of the outer surface heat exchange tubes is lower than that of the inner surface heat exchange tubes, and the dry pipes of the inner and outer surface heat exchange heat tubes are connected through connecting pipes. Due to the effect of solar heat radiation, the temperature of the working medium in the heat pipe on the outer surface rises, and it evaporates from a liquid state to a gaseous state. Due to the action of gravity, it rises into the heat exchange heat pipe on the inner surface, and becomes a liquid state after releasing heat in the room, and then returns to the outer surface for heat exchange. The heat pipe completes an endothermic and exothermic process. On the connecting pipe between the indoor and outdoor surfaces, install an intelligent controller that can achieve a single heating cycle function to realize a single heating cycle from outdoor to indoor. If the heating direction is opposite, the valve will be automatically locked. The lock valve is closed in summer. the

Summer Implementation Plan

Heat exchange tubes are installed on the inner and outer surfaces of the north wall of the building. The height of the heat exchange heat tubes on the inner surface is lower than that of the outer surface heat exchange tubes, and the dry pipes of the inner and outer surface heat pipes are connected through connecting pipes. When the indoor temperature is higher than the outdoor temperature, the temperature of the working medium in the heat exchange heat pipe on the inner surface rises and evaporates from a liquid state to a gaseous state. Due to the action of gravity, it rises into the heat pipe on the outer surface and turns into a liquid state after releasing heat to the outdoor environment, and then returns to the inner surface. The surface heat exchange heat pipe completes an endothermic and exothermic process. If the heat transfer direction is reversed, the valve is automatically locked. The lock valve is closed in winter. the
