Description
本发明涉及一种储热介质，特别是应用于蓄热蓄冷系统的储热介质。The invention relates to a heat storage medium, in particular to a heat storage medium applied to a heat storage and cold storage system.
目前，在城市建筑物中，空调用电量约占总耗电量的50％，预计到2000年，我国电力系统电网的峰谷差(或所需调峰量至少有上千万瓦，若采用储能空调，在用电低谷时储能，在用电高峰时释放能量，则可起到削峰平谷，平衡电网的作用，大力推广储能空调对平衡电力系统，节能降耗有非常重要的作用。At present, in urban buildings, the power consumption of air conditioners accounts for about 50% of the total power consumption. Energy storage air conditioners are used to store energy during low power consumption and release energy during peak power consumption, which can play a role in peak shaving and valley balance and balance the power grid. Vigorously promoting energy storage air conditioners is very important for balancing power systems, saving energy and reducing consumption. role.
中央空调系统的蓄冷方式一般包括：(1)水蓄冷；(2)冰蓄冷；(3)共晶盐蓄冷；(4)气体水合物蓄冷等。前三种蓄冷方式或蓄冷密度太低，或难于与空调的制冷工况相匹配，或储、释放冷过程热交换性能差，从而限制了其推广应用。气体水合是一种气体或挥发性液体与水作用时造成水在高于其冰点温度结晶固化的现象，水结晶时，释放出水合反应热，气体水合物的反应热(结晶相变热)较大(与冰的融化热相当)，传热性能好，且相变温度与一般空调工况相适应，被认为是理想的储能材料。目前，用于生成气体水合物的物质主要是单一工质，如CCl2F2(R12),CCl3F(R11)，CBr2F2(R12B2)等，但是，上述物质为CFC物质，对大气臭氧层有破坏作用，已经被禁止使用。为满足环保要求，HFC(氟代烃)类单质气体水合物相继提出，如HFC-134,HFC-245fa等。但这些单质气体水合物用于储热能时，其相变温度、压力不能很好地满足实用需要。The cold storage methods of the central air-conditioning system generally include: (1) water cold storage; (2) ice cold storage; (3) eutectic salt cold storage; (4) gas hydrate cold storage, etc. The first three cold storage methods are either too low in cold storage density, or difficult to match the cooling conditions of air conditioners, or have poor heat exchange performance in the process of storing and releasing cold, thus limiting their popularization and application. Gas hydration is a phenomenon in which water crystallizes and solidifies at a temperature higher than its freezing point when a gas or volatile liquid interacts with water. When water crystallizes, the heat of hydration reaction is released, and the reaction heat of gas hydrate (crystal phase change heat) is relatively high. Large (equal to the melting heat of ice), good heat transfer performance, and the phase transition temperature is compatible with general air conditioning conditions, it is considered to be an ideal energy storage material. At present, the substances used to generate gas hydrates are mainly single working substances, such as CCl 2 F 2 (R12), CCl 3 F (R11), CBr 2 F 2 (R12B2), etc. However, the above substances are CFC substances. Atmospheric ozone layer damage, has been banned. In order to meet the requirements of environmental protection, HFC (fluorocarbon) elemental gas hydrates have been proposed one after another, such as HFC-134, HFC-245 fa , etc. However, when these elemental gas hydrates are used for thermal energy storage, their phase transition temperature and pressure cannot well meet the practical needs.
