Abstract

An external cold and heat balance system combining a lithium bromide unit and a cold storage comprises a compressor (1), a heat-source side heat exchanger (2), a thermostatic expansion valve (3), a cold-source side heat exchanger (4) and a liquid-vapor separator (5) which are connected in series by pipelines. The heat-source side heat exchanger (2) and the lithium bromide unit (8) are connected in series, and the cold-source side heat exchanger (4) and the cold storage (11) are connected in series. In heating, the cold of the cold-source side is efficiently used by being transferred to an external cold balancer, i.e. the cold storage (11) or other cold-use terminals, by a heat exchange apparatus via coolant like air or water. In cooling, the heat of the heat-source side is efficiently used by being transferred to an external heat balancer, i.e. the lithium bromide unit (8) or other heat-use terminals, by a heat exchange apparatus via coolant like air or water. The cold and the heat in the cold and heat balance system are separated and circulated in balance. In the state without heat exchange with the external system, there is no waste of energy in operation as the cold and the heat circulated in balance are output synchronously by the balance of the external balancer of the system.

一种溴化锂机组与冷库结合使用的冷热外平衡*** 技术领域  Cold and heat external balance system using lithium bromide unit combined with cold storage
[0001] 本发明属于新能源与节能环保领域， 提供了一种溴化锂机组与冷库结合使 用的冷热外平衡***， 是一种涉及将***中的冷量和热量分离并平衡循环， 在无 与外界外***换热的状态下， 通过***外平衡器平衡， 同步输出循环平衡的冷量 和热量， 运行中无能量浪费的冷热平衡***。  [0001] The present invention belongs to the field of new energy, energy conservation and environmental protection, and provides a cold and heat external balance system used in combination with a cold storage unit and a cold storage, which is a method for separating and balancing the cooling amount and heat in the system. In the state of heat exchange between the external and external systems, the balance is balanced by the external balancer of the system, and the cooling and heat balance of the circulating output is synchronized, and the cooling and heat balance system without energy waste is operated.
[0002] 背景技术  BACKGROUND OF THE INVENTION
[0003] 《"十二五" 国家战略性新兴产业发展规划》中指出， 加快发展技术成熟、 市场竟争力强的核电、 风电、 太阳能光伏和热利用、 页岩石、 生物质发电、 地热 和地温能、 沼气等新能源、 积极推进技术基本成熟、 开发潜力大的新型太阳能光 伏和热发电、 生物质气化、 生物燃料、 海洋能等可再生能源技术的产业化， 实施 新能源集成利用示范重大工程。 到 2015年， 新能源占能源消费总量的比例提高到 4. 5%， 减少二氧化碳年排放量 4亿吨以上。 到 2015年， 我国节能潜力超过 4亿吨 标准煤， 可带动上万亿元投资， 节能服务业总产值可突破 3000亿元。 但是， 新能 源应用也面临节约成本和保护环境的问题。 因此， 认清能源的本质是解决如何最 有效地用物理或化学的方式供应冷热电三种基本物质， 已成为新能源和节能环保 技术和产业发展的关键。  [0003] The "Twelfth Five-Year Plan for the Development of Strategic Emerging Industries" states that the development of nuclear power, wind power, solar photovoltaic and thermal utilization, shale, biomass power, geothermal and New energy sources such as geothermal energy and biogas, and actively promote the industrialization of new energy technologies such as solar photovoltaic and thermal power generation, biomass gasification, biofuels, and ocean energy, which are basically mature in technology and have great potential for development, and implement demonstration of new energy integration and utilization. Major projects. By 2015, the proportion of new energy in total energy consumption will increase to 4.5%, and the annual carbon dioxide emissions will be reduced by more than 400 million tons. By 2015, China's energy-saving potential exceeds 400 million tons of standard coal, which can drive over one trillion yuan of investment. The total output value of energy-saving service industry can exceed 300 billion yuan. However, new energy applications are also facing cost savings and environmental protection issues. Therefore, recognizing the essence of energy is to solve the most effective use of physical or chemical methods to supply three basic substances of cold and heat, which has become the key to the development of new energy and energy-saving technologies and industries.

In the heating process, the replaced cooling capacity is not only effectively used, but also needs to be equipped with a variety of devices and suitable environment to discharge; in cooling, the displaced cooling capacity is not effectively used, but also needs to be equipped with various devices and suitable environment. To discharge. This has led to widespread phenomena in industrial, commercial, defense, aquaculture and residential life: On the one hand, the loss of a large amount of waste cold and cooling in the heating of heat requires costly disposal, on the other hand, it also requires energy and cooling. If the lost heat and cold energy can be effectively utilized, the amount can be used in industrial production and daily life, which can double the energy use efficiency and greatly reduce the energy use cost and ecological environment damage.
