Solar energy adsorptive central air conditioning cooling tower

Abstract

Solar energy belongs to refrigeration and building circumstance and equipment engineering technical field which includes solar energy collector, two activated carbon adsorption beds, condensing heat exchanger, throttle valve, evaporating heat exchanger, axial flow fan, padding, shell, spray header, air inlet, air outlet, exhaust pipe and twelve control valve, methyl alcohol steam desorpted by a adsorption bed which works using solar energy flows into the condensing heat exchanger6 is cooled by wet air, changed to liquid state methyl alcohol with low temperature, then enters the evaporating heat exchanger under gravity action cooled down through evaporating heat exchanger, liquid state methyl alcohol in the evaporating heat exchanger is evaporated with heat absorption through another 3adsorption bed, then cool the cooled water which has passed padding ulteriorly. The invention can improve refrigerating unit, raise coefficient of performance, reduce energy cost of refrigerating unit, plays significant role in energy saving of central air conditioning system and has notably social and economic benefit.

Description

technical field [0001] The invention relates to a central air-conditioning cooling tower, in particular to a solar energy absorption central air-conditioning cooling tower, which belongs to the technical fields of refrigeration engineering, building environment and equipment engineering. Background technique [0002] The cooling tower is an important part of the central air-conditioning system. Its function is to continuously discharge the condensation heat of the refrigeration unit to the environment by cooling the condenser of the refrigeration unit to meet the normal operation of the refrigeration unit. The condensation temperature of the refrigeration unit is closely related to the outlet water temperature of the cooling tower. When the cooling water flow rate is constant, the lower the outlet water temperature of the cooling tower is, the lower the condensation temperature of the refrigeration unit will be, thereby increasing the refrigeration coefficient of the refriger...

AI Technical Summary

Problems solved by technology

Although these cooling tower invention patents can reduce the outlet temperature of cooling water by improving heat exchange efficiency, they are ultimately affected by the outdoor air temperature

In the hot summer, when the outdoor temperature is high, the heat transfer efficiency of these structurally improved cooling towers will inevitably decrease.
