Abstract

The invention provides a drainage device of evaporator condensate water and a drainage method. The drainage device of the evaporator condensate water comprises a drainage pump, a controller connected with the drainage pump and a liquid level sensor used to detect the liquid level of the condensate water, wherein the liquid level sensor is connected with the controller, and after the controller detects that the liquid level of the condensate water reaches the high water level limit, the controller controls the drainage pump to stop draining water after the drainage pump works for a preset water discharge time t1. By adopting the technical scheme, the drainage pump stops work after the drainage pump works for the preset water discharge time t1, and the drainage device of the evaporator condensate water and the drainage method help to solve the problems that noise is large, energy is not observably saved and the like in the prior art.

Description

technical field [0001] The invention relates to the field of refrigeration units, in particular to a drainage device and a drainage method for condensed water of an evaporator. Background technique [0002] In the prior art, the control of the water pump during the cooling process of the unit generally adopts the normally open mode, that is, the water pump is always on during the cooling operation of the unit, and does not stop running until the unit is turned off. [0003] There is following shortcoming in prior art: [0004] 1. Since the condensed water produced on the evaporator is less than the displacement of the drainage pump, the drainage pump will not be able to absorb the condensed water for a period of time. When the pump sucks in air, it will make an abnormal noise of pumping water from the drain pump. figure 1 The noise spectrum diagram of the prior art evaporator condensate drainage device is shown. [0005] 2. The drainage pump is always on when the refriger...
