Method for collecting latent heat of solidification of cold water

Abstract

The invention discloses a method for collecting the latent heat of solidification of cold water, belongs to the technical field of energy, and aims to provide a method for collecting the latent heat of solidification of the cold water, which realizes the purpose that the latent heat of solidification is extracted from the cold water and supplied to the outside. According to the method for collecting the latent heat of solidification of the cold water, two sides of a wide cold water runner are iced up, and then a scraper is continuously rotated to remove and discharge ice, so that unblocking of the cold water runner is guaranteed; and furthermore, by combination of thermal ice melting and mechanical ice discharging, continuous circulation of continuous icing, deicing, ice discharging and icing again of the cold water is guaranteed, and continuous and stable extraction of the latent heat of solidification of the cold water for external heat supplying is realized. The method has the outstanding advantages of simple process form, reliability and stability, and is applicable to a heat supply system of a heat pump using the latent heat of solidification.

Description

technical field [0001] The invention relates to a collection method for latent heat of cold water solidification which releases latent heat when cold water freezes to supply heat to the outside, and belongs to the technical field of energy. Background technique [0002] Using heat pump technology to extract low-grade cold heat from water sources to provide heating and cooling for buildings has huge energy saving, environmental protection and economic value, and is one of the important ways to save energy and reduce emissions. However, due to the limitation of water sources, there is no water source in places that need heating, and there may be no buildings in places with a large amount of water sources, which limits the application of water source heat pumps. If the latent heat of solidification released when cold water freezes can be effectively extracted, the water consumption can be greatly reduced, because water at 0°C becomes ice at 0°C, which means that the temperature...

Problems solved by technology

This technical solution has complex mechanical processes and high processing accuracy requirements. In addition, relying entirely on mechanical ice scraping not only requires a lot of mechanical work, but also consumes a lot of energy, and the later operation and maintenance are also more difficult.

[0006] The patent number is "201210436817.4", the name is "ice storage cold water heat storage system", and the patent publication number is "CN102927638A". It is used for cooling at night and used during the day, and the efficiency is very low. It is different from extracting the latent heat of cold water solidification. continue to operate

[0007] The patent applied by the inventor, the application number is "201610701458.9", the name is "a heat pump heating and cooling system for extracting solidification heat or ice making", the patent uses solid-liquid fluidized bed and cyclone desanding process for online Ice making and deicing, in the actual operation, due to the rapid formation of the ice layer, the ice layer cannot be peeled off in time and effectively under the impact of the sand, and the continuous and stable extraction of the latent heat of solidification cannot be achieved.
