Problems solved by technology

On the other hand, although the mechanical air-conditioning system can reduce the indoor temperature to meet the comfort requirements of the indoor occupants, due to the influence of the external environment on the outer enclosure structure, the temperature of the inner surface of the outer enclosure structure is higher, causing serious harm to the indoor occupants. Significant heat or cold radiation which greatly reduces human comfort

Embodiment 1

[0043] Such as figure 1 As shown, the ducted air-conditioning system embedded in the enclosure structure using renewable energy of the present invention is suitable for hot summer and cold winter regions. The system includes a building heat exchange part 1 , an energy storage part 2 , an auxiliary cold source part 3 , an auxiliary heat source part 4 and a power transmission part 22 .

[0044]During the heating season, when the measured outdoor temperature 19 is lower than the maximum outdoor temperature during winter heating, valves 13 and 14 are opened, other valves 32, 33, 42, and 43 are closed, and the power delivery part 22 (generally a water pump) ) is opened to provide water higher than the temperature of the outdoor environment to the pipes 11 and 12 in the enclosure structure, reducing the heat dissipation from the room to the outside and playing a role in resisting the cold. The borehole heat exchanger 21 lowers the soil or aquifer 2 temperature. If the measured tem...

Embodiment 2

[0049] Such as Figure 4 As shown, this embodiment is a variant system obtained by canceling the auxiliary cooling source in the system of embodiment 1, and is suitable for regions with cool summer and cold winter, that is, regions that do not need cooling in summer but require heating in winter. The system includes a building heat exchange part 1 , an energy storage part 2 , an auxiliary heat source part 4 and a power transmission part 22 . The operating mode of the system in the heating season in winter is the same as the heating operating mode of Embodiment 1. The operation mode of the heat storage season in the autumn using the auxiliary heat source for heat storage is the same as the heat storage operation mode of Embodiment 1. The system does not have a summer cooling mode and a cold storage operation mode using an auxiliary cold source for cold storage.

Embodiment 3

[0051] Such as Figure 5 As shown, this embodiment is a variant system obtained by partially canceling the auxiliary heat source in the system of embodiment 1, and is suitable for hot summer and warm winter regions, that is, regions that require cooling in summer but do not need heating in winter. The system includes a building heat exchange part 1 , an energy storage part 2 , an auxiliary cold source part 3 and a power transmission part 22 . In the cooling season in summer, the operating mode of the system is the same as the cooling operating mode of Embodiment 1. In winter and / or spring, the operation mode of the cold storage season using the auxiliary cold source for cold storage is the same as the cold storage operation mode of Embodiment 1. The system does not have a winter heating mode and a heat storage operation mode using auxiliary heat sources for heat storage.

Abstract

The invention discloses an embedded pipeline air-conditioning system of envelop enclosure and control method thereof, which belongs to the field of green air conditioning capable of using renewable low grade energy. The air-conditioning system includes a building heat exchange part, an energy storage part, an auxiliary cold source part, an auxiliary heat part, and a power conveying part. The invention embeds a pipeline in an envelop enclosure to enlarge the heat exchange area between a circulating fluid and the envelop enclosure so as to realize low temperature difference heat transmission when directly using the renewable low grade energy and obtain a large heat exchange volume so as to realize the direct storage of heat and cold energy simultaneously when heating and cooling, captures the renewable low grade energy through the auxiliary cold source part and the auxiliary heat part, and implements storage through the energy storage part so as to further improve the heating and cooling capacities of the system. The air-conditioning system can sufficiently use the renewable energy to reduce the influence of outdoor climate to the indoor environment, thereby greatly reducing and even canceling the dependence upon high grade energy for meeting the indoor comfort requirements.

Description

Technical field: [0001] The invention belongs to the field of green air-conditioning utilizing renewable low-grade energy, and in particular relates to an air-conditioning system with pipelines embedded in an enclosure structure and a control method thereof. Background technique: [0002] Due to the development of mechanical refrigeration technology and the improvement of living standards, the application of mechanical comfort air conditioning systems that consume high-grade energy such as electricity and gas is becoming more and more extensive. The energy consumption of building operation in my country continues to rise, and the energy consumption of building operation accounts for 18.8% of the total energy consumption of the society. In the past period of time, problems such as global warming, the destruction of the ozone layer, and the increase in the consumption of fossil fuels have forced society, experts, and the industry to seriously think about how to effectively red...
