The invention discloses a natural ice cold-storage and water-storage system and a circulation method. The natural ice cold-storage and water-storage system is composed of an underground ice storage chamber, a heat exchanger, a first circulation pump, a second circulation pump, a fan coil, a first valve, a second valve, a third valve, a fourth valve, a fifth valve, a sixth valve, a seven valve and an eighth valve which are connected via pipelines to form the cold-storage and water-storage system, wherein a heat exchange coil is arranged at the bottom of the underground ice storage chamber; a plurality of plate-shaped stainless steel mesh frames are arranged on the heat exchange coil; and the stainless steel mesh frames are supported on the heat exchange coil via supports, and used for protecting the heat exchange coil from the impacting-pressing of ice blocks. The natural ice cold-storage and water-storage system is used for storing the collected natural ice blocks in the underground ice storage chamber in winter, supplying cold for rooms during air-conditioning periods in summer and providing water for irrigation during drought seasons in autumn; a glycol aqueous solution is used as an ice-melting heating medium in the system, and two circulation methods, i.e., a single-circulation method and a double-circulation method, are implemented; and via the natural ice cold-storage and water-storage system, sharing for end equipment for cold supply in summer and end equipment for heat supply in winter can be realized.
Description
technical field [0001] The invention relates to a natural ice cold storage water storage system and a circulation method, in particular to a method of collecting natural ice cubes in winter and storing them in underground ice storage chambers, cooling rooms by melting ice in summer, and using melted water in autumn for gardens and agriculture A natural ice cold storage water storage system for irrigation and a circulation method. Background technique [0002] After more than 150 years of development, compression refrigeration technology has become mature. The application of freon refrigerants has enabled the widespread promotion of compression refrigeration and air conditioning, especially the penetration of automatic control technology and other related technologies. The precision and automation of compression refrigeration and air conditioning technology With the development of social economy, compression refrigeration air conditioners are rapidly popularizing in urban and...
