Description
Technical Field
The present invention relates generally to the field of air conditioning technology and, more particularly, to a system for improving the refrigeration performance of an air-cooled air conditioning unit by using the end condensate water of an air conditioner, and an air-cooled air conditioning unit.
Background
With the development of society and the continuous improvement of the living standard of people, the air conditioner has gone into thousands of households. At present, a household split type air conditioner, a commercial central air conditioner (VRV), and a commercial and residential air-cooled heat pump type air conditioner may be referred to as an air-cooled air conditioner set. The air-cooled air conditioning unit generally sucks air through an axial flow fan, so that the air flows to perform forced heat exchange with the fins, and the purposes of cooling the fins and maintaining the unit for refrigeration are achieved. When the unit operates, air transversely sweeps across the fins, heat conducted to the surfaces of the fins by the refrigerant is taken away, and the temperature of the air is increased along with the heat. When the temperature of the air is close to or even with the temperature of the surfaces of the fins, the heat on the fins cannot be dissipated, the unit is protected at high temperature, and then the compressor stops refrigerating. In addition, because the specific heat (1.0 kj/(kg ℃)) of the air is small, and the heat taken away in unit time is small under the condition of a certain flow rate, the Energy Efficiency (EER) of the air-cooled air conditioning unit during refrigeration is generally about 3.0 (under the standard condition), the difference from the water-cooled unit is large, and the refrigeration energy efficiency EER of the water-cooled unit is about 5.5 (under the standard condition).
The air temperature is high in summer, the air humidity is high, the indoor air transversely passes through the surface cooler at the tail end of the air conditioner and is sent back to the room after being cooled, and the air is repeatedly circulated in the way, so that the indoor temperature is reduced. Because the temperature of the surface cooler is lower than the dew point temperature of the indoor air, a large amount of condensed water can be separated out in the circulating cooling process of the indoor air, and the temperature of the condensed water is generally about 20 ℃. Under the overwhelming majority of circumstances, the comdenstion water flows to the condensate pipe through the water-collecting tray of air conditioner terminal surface cooler below, then directly arranges to the sewer in, so not only the waste of water resource, especially the waste and the loss of air conditioner cold source.
The working temperature of the standard working condition of the cooling tower of the water cooling unit is generally 38 ℃/33 ℃, and the working water temperature is far higher than the water temperature of condensed water. When the air cooling unit is used for refrigerating, the ambient air temperature of the unit is increased due to poor circulation of air around the unit or high outdoor temperature. Under severe working conditions, the ambient air temperature of the unit can reach more than 45 ℃, and the normal operation of the unit is seriously threatened.
Based on this, the prior art still remains to be improved.
