Recycling device for condensate water of air conditioner and control method for recycling device

Abstract

The invention relates to a recycling device for condensate water of an air conditioner and a control method for the recycling device. The recycling device comprises a heat preservation water tank, a heat exchanger, a water storage tank and a control device; a condensate water temperature detection device and an environment temperature detection device are arranged inside and outside the heat preservation water tank respectively; the heat exchanger selectively communicates with the heat preservation water tank, and the surface of the heat exchanger is provided with a refrigerant temperature detection device; the water storage tank selectively communicates with the heat exchanger; and the control device is configured to enable at least part of the condensate water in the heat preservation water tank to flow into the heat exchanger and control the refrigerant temperature detection device and the environment temperature detection device to regularly detect the condensate water temperature in the heat exchanger and the environment temperature when the difference value between the environment temperature and the condensate water temperature in the heat preservation water tank is greater than a first preset temperature threshold value so that the condensate water in the heat exchanger can be discharged to the water storage tank when the difference value between the environment temperature and the condensate water temperature in the heat exchanger is less than or equal to a second preset temperature threshold value. The control method comprises the steps of temperature primary detection, cold quantity recovery, temperature timing detection and condensate water discharge.

Description

technical field [0001] The invention relates to energy-saving technology, in particular to an air-conditioning condensed water recycling device and a control method thereof. Background technique [0002] In summer, when the air conditioner is running for cooling, because the evaporation temperature of the indoor unit evaporator is lower than the dew point temperature of the circulating humid air, condensed water will be generated, and the condensed water will slide down to the water receiving tray through the fins. At present, the traditional method is to lead the condensed water out of the indoor side through the drain pipe, and introduce it to the ground through the outdoor drain pipe. This will not only cause the loss of condensed water energy, but also if the drain pipe is placed directly outside the outdoor, the condensed water will drip onto the building or the things of the neighbors downstairs, causing complaints and dissatisfaction. [0003] The temperature of the ...

Problems solved by technology

In the prior art, there are roughly two ways to use the cooling capacity of condensed water. One is to introduce condensed water to the outdoor unit to spray the condenser to cool down. This requires complex spraying devices and control systems, and the structure is complex and difficult to maintain. The other is to install a heat exchanger at the fresh air inlet or return air outlet of the air conditioner to use the cooling capacity of condensed water to cool down the fresh air or return air of the air conditioner. In this way, the temperature difference between the fresh air or return air and the condensed water It may not be obvious that the cooling capacity utilization efficiency of condensed water is low, which not only cannot effectively save energy, but also may increase energy consumption due to blindly and continuously exchanging heat between condensed water and fresh air or return air
