Dynamic ice-storage type cold-hot water energy-saving set

Abstract

This invention discloses a dynamic ice collecting type cold and hot water energy saving machine set which fully uses heat energy. It includes compressor, condenser, evaporator, cooling tower, I heat exchanger, by-pass valve, II heat exchanger, hot water tank, cooling water pump, hot water circulating pump, cooling water valve, cooling water circulating valve and ice collecting groove. The medium side of I heat exchanger and the by-pass valve are paralleled connected into the refrigerating medium pipeline between the compressor outlet and condenser. The I heat exchanger, hot water tank, hot water circulating pump and the hot water side of II heat exchanger are connected successively to form water heating circulating loop. The cooling water side inlet of II heat exchanger is connected into the refrigerating water circulating pipe between condenser and cooling water valve. Its outlet connects to the water inlet of cooling water pump. This invention can be used widely in the air conditioner energy saving field.

Description

technical field [0001] The invention relates to a dynamic ice storage type cold and hot water energy-saving unit. Background technique [0002] Air-conditioning energy storage technology is a practical and comprehensive technology that has emerged in China since the 1990s. It can shift peaks and fill valleys in the power grid, which is conducive to the optimal allocation of social resources. At the same time, due to the peak and valley electricity prices The air-conditioning energy storage technology has greatly reduced the operating electricity cost of the user, so it is a technology that benefits the country and the people. Energy-storage air conditioners use energy-storage equipment to store energy when the air-conditioning system does not need energy or use little energy, and release this part of energy when the air-conditioning system requires a lot of energy. According to the object of use and the level of storage temperature, it can be divided into cold storage air c...

AI Technical Summary

Problems solved by technology

On the one hand, when the ice-storage air-conditioning unit is in normal cooling, the condensation heat is generally discharged through the cooling system, and a large amount of heat energy is wasted; Therefore, a large amount of energy is consumed; it can be seen that the double waste of energy and resources is caused by cooling and hot water

[0005] Therefore, the existing technology has the following deficiencies: insufficient utilization of thermal energy, waste of energy
