Embodiment 1

[0038] as attached figure 1 As shown, the method of evaporative cooling in Embodiment 1 includes an indirect evaporative water chiller 7, an indoor sensible cooling terminal 1, and an air handler. The surface heat exchanger 2 of the water chiller 7 and the air handler include the surface heat exchanger 3 of the air handler, which is carried out in the following steps: the outlet water of the indirect evaporative water chiller is first sent to the indoor cooling terminal 1, eliminating the indoor After part of the sensible heat load, all the effluent water from the indoor terminal 1 is transported to the surface heat exchanger 2 of the indirect evaporative chiller, and then connected to the surface heat exchanger 3 of the air handler in series, and then returned to the indirect evaporative chiller Promptly pass into the inlet of the spray water distributor of the indirect evaporative chiller 7, thus forming a cycle work process.

Embodiment 2

[0042] as attached figure 2 As shown, the method of evaporative cooling in Embodiment 2 includes an indirect evaporative chiller 7, an indoor sensible cooling terminal 1, and an air handler. The surface heat exchanger 2 of the water chiller 7 and the air handler include the surface heat exchanger 3 of the air handler. One stream of outlet water from the cold terminal 1 is sent to the surface heat exchanger 2 of the indirect evaporative chiller, and the other stream of outlet water from the indoor cooling terminal 1 is delivered to the surface heat exchanger 3 of the air handler. The effluent from the surface heat exchanger 2 is mixed with the effluent from the surface heat exchanger 3 of the above-mentioned air handler, and then returns to the indirect evaporative chiller, that is, the inlet of the spray water distributor of the indirect evaporative chiller 7, thus forming cycle work process.

Abstract

The invention relates to the technical field of heating ventilation air conditioning, in particular to a method and a device for refrigerating and supplying cold through evaporation. The method for refrigerating and supplying cold through evaporation comprises the following steps that: the discharged water of an indirect evaporation cold water machine is transported to an indoor sensible cold tail end, after a part of indoor sensible heat load is eliminated, all discharged water of the indoor tail end is connected in series or in parallel with the surface heat exchanger of the indirect evaporation cold water machine and the surface heat exchanger of an air processor, and is returned to the indirect evaporation cold water machine, namely is fed into the inlet of the spraying water distributor of the indirect evaporation cold water machine. The method and the device have the advantages that: energy is used according to different user load characteristics and water temperature requirements, cold is supplied to the indoor sensible cold tail end, a fresh air unit and the surface heat exchanger of the indirect evaporation cold water machine, a low-to-low and high-to-high energy using mode is realized, and the energy is used more rationally, so that the supply of indirect evaporation cold water is reduced, and equipment investment is greatly lowered.

Description

Technical field [0001] The invention relates to the technical field of heating, ventilating and air conditioning, and relates to a method and a device for evaporative cooling and cooling. technical background [0002] Dry air energy evaporative refrigeration technology is to use dry air energy to obtain the cooling capacity required for air conditioning. In different types of evaporative refrigeration devices, use the heat and moisture exchange of water and dry air to obtain low-temperature cold air or (and) cold water. technology. Dry air energy evaporative refrigeration technology has been widely used in hot and dry areas, especially in Xinjiang, due to its unique advantages such as greenness, health, energy saving, environmental protection, and economy, and has achieved good application results. [0003] The Chinese patent document whose publication number is CN1435625A discloses a method and its device for indirect evaporative cooling, and the Chinese patent document wh...
