Embodiment Construction

[0029] The invention proposes an indirect evaporative refrigeration method and device for simultaneously generating cold water and cold air. figure 1 , figure 2 It is a schematic diagram of the indirect evaporative refrigeration method that simultaneously generates cold water and cold air. The principle is that the outdoor fresh air first enters the evaporative cooling heat recovery device 1 composed of n-level spray cooling modules 3, absorbs the cooling capacity generated by the exhaust air evaporative cooling process, and after being cooled, enters the evaporative cooler 2 and the evaporative cooler 2 The spray water from top to bottom is in direct contact with evaporative cooling. Part of the air from the evaporative cooler 2 is sent to the user as low-temperature fresh air under the action of the blower 5, and part of it is sent to the evaporator under the action of the exhaust fan 6. The cooling heat recovery unit 1 undergoes n-stage spray evaporative cooling in sequen...

Abstract

The invention discloses an indirect evaporation cooling method of generating cold water and cold wind at the same time and a device, belonging to the energy technical field and relating to an evaporation cooling type cold supply. Fresh air firstly enters a multistage evaporation cooling type heat recoverer, is performed with a wet cooling by an exhaust air evaporation cooling process, etc., then enters an evaporation cooler which generates the cold water and the cold wind at the same time and is performed with a direct evaporation cooling by contacting spray water; part of outlet air of the evaporation cooler is outputted to a user, while another part of the wind is used as exhaust air which is exhausted outdoor via cooling inlet air during multistage evaporation cooling process. In the evaporation cooler, the cold water is outputted after circulated and cold water of the user is cooled by the spray water and an air evaporation cooling process; a temperature of outlet water is lower than a wet bulb temperature of inlet air. The invention outputs the cold water for the user and the fresh air at a lower temperature at the same time, solves a mismatching of a flow ratio of air and water in a sensible heat transferring process and a heat and moisture exchanging process, and solves the mismatching caused by a non linearity of a saturated line through a multistage device; a cold water side for the user can be a closed system, and application situations for a unit can be more widely.

Description

technical field [0001] The invention belongs to the field of energy technology, and in particular relates to an indirect evaporative refrigeration method and device for simultaneously generating cold water and cold air for evaporative cooling. Background technique [0002] According to the difference of cooling medium, there are two main ways to apply evaporative cooling technology at present: generating cold air and generating cold water. Among them, the way of using evaporative cooling to generate cold air was developed earlier, such as (multi-stage evaporative refrigeration air conditioner (ZL 99259083.3), indirect evaporative refrigeration air conditioner (ZL 99258508.2), etc.). system, the air duct takes up a lot of space, and the power consumption of the fan is high, which limits the application of evaporative cooling technology. In ZL 02100431.5 "A Method and Device for Indirect Evaporative Cooling", the invention and successful development of an indirect evaporative...
