Abstract

The invention provides a tubular device and a method for producing cold water by means of indirect evaporation and direct evaporation. The tubular device is characterized in that the air which enters from a wind inlet (16) is firstly cooled by an air cooler (8) by means of constant wetness, the air enters a tubular indirect heat exchanger (7) to be secondly cooled by means of constant wetness, the air which is secondly cooled by means of constant wetness enters from the bottom of a lower direct evaporator cooler (10) through a wind return chamber (9), sequentially passes through the space between the lower direct evaporator cooler (10) and the tubular indirect heat exchanger (7) and an upper direct evaporator cooler (6) from down to top to exchange the heat with spray water by convective transfer mass to produce the cold water for a user, the return water used by the user is used for cooling the air which firstly enters from a wind inlet (16) through the air cooler (8) by means of constant wetness, and the nearly-saturated or saturated wet air is discharged by an exhaust fan (3) through a wind outlet (2), so that the circulatory refrigeration is realized. The water is taken as a refrigerant, a mass of refrigerants can be saved, the use cost of the user can be lowered, and the environment can not be polluted, so that the tubular device is low-carbon and energy-saving.

Description

technical field [0001] The invention relates to the field of water evaporation refrigeration equipment and energy technology, in particular to a method and device for producing cold water by tube-type indirect evaporation and direct evaporation. Background technique [0002] In the prior art, the method of producing cold water by using evaporative cooling technology is to use water to contact with unsaturated air, and to cool down the air or water through the evaporation of water. It uses the "dry air energy" of the atmosphere itself as the driving force. It is a passive cooling method and a simple application of direct evaporative cooling. Therefore, the utilization rate of air is low, energy is wasted, and the effect of producing cold water is relatively low. Difference. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies of the existing technology, and provide a dual technology of indirect evaporation and direct evaporat...
