Technology for reducing condenser temperature by evaporator tail end remaining cold energy

Abstract

The invention provides a technology for reducing the temperature of a condenser by the residual refrigeration at the tail end of an evaporimeter, which is characterized in that, in a refrigerating equipment, a fixed water tank is built in; a pipeline coil from the tail end of the evaporimeter to a liquid-storage tank and a pipeline coil from the tail end of the evaporimeter to a drying filter are arranged in the fixed water tank; the residual refrigeration in the pipeline from the tail end of the evaporimeter to the liquid-storage tank and returning to the compressor is taken used to exchange heat with the not-dropped high temperature at the tail end of the condenser after air cooling by taking water as transmission media, so as to reduce the temperature of the condenser. The invention is of simple process structure, easy to install, can save energy by taking use of the residual refrigeration in the pipeline from the tail end of the evaporimeter to the liquid-storage tank and returning to the compressor. The water cooling in the invention is fundamentally different from the water cooling in prior technology, the certain amount of water added once can be used in a circulating way for years, and a lot of water can be saved. As the temperature dropping of the condenser is solved timely, not only the refrigeration efficiency can be improved, but also the impedance of the compressor can be reduced efficiently, the service life of the refrigeration equipment can be prolonged.

Description

1. Technical field [0001] The invention relates to a technique for lowering the temperature of the condenser by utilizing the residual cooling at the tail end of the evaporator and the tail end of the condenser to perform cold and heat exchange through water circulation. 2. Technical Background [0002] The current condensation methods of refrigeration equipment mainly include three forms: air cooling, water cooling, and wind-water co-cooling. The air-cooled cooling condenser is the most commonly used method because of its simple method, but it has relatively high requirements on the ambient temperature. If the ambient temperature is high, its cooling effect will drop significantly, or even stop cooling, resulting in the phenomenon that the refrigeration equipment does not cool in high temperature seasons. ; In addition, the high temperature makes it impossible for the refrigerant in the condenser to change from gaseous state to liquid state, and the pressure of the refriger...

The air-cooled cooling condenser is the most commonly used method because of its simple method, but it has relatively high requirements on the ambient temperature. If the ambient temperature is high, its cooling effect will drop significantly, or even stop cooling, resulting in the phenomenon that the refrigeration equipment does not cool in high temperature seasons. ;In addition, the high temperature makes it impossible for the refrigerant in the condenser to change from gaseous state to liquid state, and the pressure of the refrigeration pipeline increases to form resistance and damage the compressor

[0003] The water cooling method of small and medium-sized refrigeration equipment is mainly to use well water or tap water for one time. In summer, the water temperature is lower than the air temperature to reduce the temperature of the condenser. However, this method will waste a lot of water resources, which is neither economical nor practical, so it has not been promoted. use

[0004] ZL002332159 discloses a wind-water co-cooling technology. This technology uses air cooling when the temperature is low, and uses wind and water co-cooling when the temperature is high to reduce the temperature of the condenser to the setting range. However, this technology still does not get rid of the temperature above 25°C. The result of massive waste of water resources in high temperature season
