Abstract

The invention discloses an evaporative cooling unit control method and device and air conditioning equipment. The method comprises the steps that the inlet and outlet temperature difference T of an evaporative cooling unit is measured; when the inlet and outlet temperature difference T is not within a preset temperature difference value range, the frequency of a fan and / or the frequency of a waterpump are / is adjusted so that the inlet and outlet temperature difference T can be within the preset temperature difference value range; and when the inlet and outlet temperature difference T is within the preset temperature difference value range, the current fan frequency and the current water pump frequency are kept. By means of the method, a heat exchange coil can be prevented from forming dryspots, the water consumption in the refrigeration process is reduced, the situation that refrigeration cannot be implemented due to nozzle blockage is prevented, and the applicability of the evaporative cooling unit in different areas is improved.

Description

Technical field[0001]The present invention relates to the field of unit control, and in particular, to an evaporative cooling unit control method, apparatus, and air conditioning apparatus.Background technique[0002]Evaporative cooling air conditioning techniques are techniques for evaporating heat absorption using water. Under conditions without any other heat sources, the hot and humid exchange process between water and air is air to pass the heat to water, and the temperature of the air is lowered. Due to the evaporation of water, the moisture of air is not only increased, but also into the air vapor into some vaporization. As long as the air is not saturated, the effect of cooling can be obtained by directly (or by the filler layer). When the conditions are allowed, the cooling air can be used as a blow to reduce the room temperature, and the method of treating air is referred to as evaporative cooling air conditioning.[0003]Evaporative cooling units have increased significantly ...
