Problems solved by technology

Although the cold storage technology has been widely used in the air-conditioning industry and has obvious energy-saving benefits, it cannot be applied in the air-conditioning cold storage mode because the temperature of the cold source for cold storage is tens of degrees different from the temperature of the cold storage.

Abstract

The present invention is an energy-storage circulating cooling technology for a water-cooled condenser in a cold storage. An ice accumulator is installed in the circulating water pool of the refrigeration system. One or more sets of ice storage pipes are connected to the input end of the compression condensing unit in the cold storage refrigeration system through the ammonia liquid separator, and form an independent cold storage system with the cooling tower. The advantages of the present invention: the ice storage device is installed in the circulating water pool to reduce the cooling water temperature in summer by 10°C on average, reaching 25°C; the condensation pressure is reduced by 0.2mpα on average, reaching 1.0mpα, the comprehensive energy consumption is reduced by 15-30%, and the efficiency ratio is COP The value is increased by about 30%. It uses the national peak and valley electricity price policy to store the circulating cooling water of the condenser during the low-valley electricity price period, and convert energy during the peak electricity period, thereby reducing the condensation pressure, increasing the efficiency ratio COP value, and achieving the safe use of the refrigeration system in high-temperature seasons , and reduce power consumption by 15-30%.

Description

technical field [0001] The invention relates to a cold storage water-cooled condenser energy storage type circulating cooling technology suitable for large and medium-sized cold storage, and belongs to the technical field of energy storage refrigeration. Background technique [0002] The existing technology is to convert all the heat of the cold storage through the water-cooled condenser and the cooling water, and the circulating cooling water relies on the cooling tower to maintain a temperature difference of 3-5°C. With the increase of ambient temperature and the current global warming effect, due to the increase of cooling water temperature in most cold storage in summer, the corresponding condensation pressure also increases, usually around 1.4mpα, or even close to the limit pressure of 1.55mpα. Condensing pressure is a key parameter of refrigeration efficiency, which depends on the cooling water temperature and is inversely proportional to the efficiency ratio COP value...
