Description

Heat energy generation and storage integrated indoor temperature control cold and hot supply system
Technical Field
The invention relates to the fields of heat energy generation and storage, indoor temperature control and heat energy supply, in particular to an integrated indoor temperature control cold and heat supply system for heat energy generation and storage based on thermochemistry and phase change energy storage.
Background
Indoor temperature control and commercial heating/cooling consume a large amount of electric power. According to the data of the national statistical bureau, the electricity consumption of the Chinese residence accounts for 13.7% of the total electricity consumption of each industry in 2016, wherein the electricity consumption of indoor heating and refrigeration accounts for about 31%. The power consumption of wholesale and retail industries occupies 3.7 percent of the total power consumption, wherein the power consumption for commodity refrigeration and fresh-keeping and indoor temperature control also occupies about 31 percent. The house in south China mostly adopts an air conditioner or an electric heater for heating in winter, and adopts an air conditioner for cooling in the south and north China for cooling in summer. The wholesaler and the retailer mostly adopt a compression refrigerator when refrigerating the fresh-keeping goods. When a user uses a traditional air conditioner, an electric heater or a compression refrigerating machine, the air conditioner, the electric heater or the compression refrigerating machine can be started only during use, so that high electric charge can be caused during use in peak electricity utilization periods in the daytime, and huge pressure can be caused to a power grid during the peak electricity utilization periods in high-temperature and/or low-temperature weather and the like. In addition, most of the conventional air conditioners, electric heaters or compression refrigerators are selected according to peak load requirements, and the actual load requirements are about half of the peak requirements, thereby causing resource waste. Furthermore, conventional air conditioning refrigeration often uses environmentally unfriendly refrigerants.
In order to reduce the power consumption during peak periods of power consumption, realize peak clipping and valley filling and reduce the electricity cost of customers, an energy storage electric heater based on a phase change material or a sensible heat material or an air conditioner and a refrigerator provided with an energy storage unit are mostly considered at present, so that the electric power is used for generating and storing heat energy or cold energy during the valley periods, and the stored heat energy or cold energy is released during the peak periods. However, these energy storage air conditioners or electric heaters based purely on phase change materials or sensible heat materials have the problem of low energy density, resulting in higher volume and quality than conventional air conditioning systems, and cannot achieve heat energy production by themselves. Meanwhile, the difference between the thermal energy storage temperature and the ambient temperature is large, the energy storage time is short, and the thermal energy storage time is difficult to maintain for 1-2 weeks even under the condition of using a high-cost thermal insulation material. In addition, although there have been many studies on green refrigerants (e.g., CO) in recent years2) However, the energy efficiency ratio is low, the system cost is high, and the market competitiveness is weak. Therefore, there is a need for new technologies for generation, storage and supply of thermal energy with high energy storage density, high resource and energy utilization efficiency, high energy efficiency ratio and low system cost.
