Description
Technical Field
The invention relates to the technical field of air conditioning for household, commercial and/or industrial application, in particular to a condensate water recovery device, a control method and an air conditioner.
Background
Air conditioners are also known as air conditioners and are called air conditioners for short. Generally, an air conditioner is an electric appliance capable of adjusting and controlling the temperature of air in a certain space (e.g., in a building). In certain cases, the air conditioner may also have functions of providing air purification, adjusting air humidity, and the like. In the existing air conditioners for domestic, commercial and industrial applications, the split air-cooled air conditioner is widely applied.
The split type air-cooled air conditioner includes an indoor unit and an outdoor unit connected together by a duct or the like, wherein the outdoor unit generally includes a compressor for compressing a refrigerant and a condenser as a heat exchanger.
Fig. 1 is a schematic view of an outdoor unit of a split type air-cooled air conditioner in the related art. As shown in fig. 1, a conventional outdoor unit is equipped with an air-cooled heat exchanger including a blower fan shown by a dotted line, and has a simple structure using the atmosphere as a heat source, and can generally satisfy performance requirements.
The evaporation module of the existing evaporative condenser is arranged in the machine, water naturally drops on the finned-free coil, and under the driving of the fan, an air circulation system is formed in the machine, so that the water on the surface of the coil is evaporated, and the condensation effect is achieved.
However, the existing evaporative condenser has high requirements on the water quantity configuration and the water spraying mode of the spray water, and all cooling water is required to wet the coil and form a continuous water film so as to obtain the maximum heat transfer coefficient. The existing evaporative condenser has large heat exchange area requirement, so the length of the coil pipe is very long, and the occupied area of the system is large. The existing evaporative condenser has the structure that a fan motor and other parts working with electricity operate in a high-temperature and high-humidity environment because a large amount of cooling water is evaporated in the machine, and the requirements on moisture resistance and insulation grade are high. The existing evaporative condenser needs a set of independent cooling water circulation system, has a complex structure, and cannot be carried by a small split air conditioner. The heat transfer coefficient of an outdoor air-cooled heat exchanger is small, the outdoor air-cooled heat exchanger is used for refrigerating or heating when the ambient temperature is high, the heat exchange efficiency of the heat exchanger often cannot meet the performance requirement, the refrigeration cycle is deteriorated, and the performance of the air conditioner, COP (coefficient of performance), namely the ratio of heating capacity to effective input power when the air conditioner performs heat pump heating operation under the rated working condition (high temperature) and the specified condition, is represented by W/W), EER (energy efficiency ratio, the ratio of refrigerating capacity to effective input power when the air conditioner performs refrigerating operation under the rated working condition and the specified condition, is represented by W/W) and other characteristic parameters are greatly reduced, so that the condition of insufficient refrigerating or heating performance occurs. When the existing split air-cooled air conditioner is just started in a refrigerating or heating mode, a control system needs a certain time to adjust each module to the optimal operation state, and the refrigerating or heating performance is usually insufficient in the time. The existing split air-cooled air conditioner operates in heating mode when the atmospheric temperature is low, and the outdoor heat exchanger frosts after a period of time, so that the heating performance is seriously influenced. The existing split air-cooled air conditioner produces condensed water which is directly discharged through a condensed water pipe under a refrigeration or heating mode, and the problems of water dripping, water accumulation and the like are caused. The outdoor heat exchanger of the existing split air-cooled air conditioner is exposed in the atmospheric environment all the year round, and the gaps among the fins are easily blocked due to the influence of sand, dust, rainwater and the like, so that the heat exchange efficiency of the heat exchanger is reduced.
Therefore, how to design a condensate water recycling device, a control method and an air conditioner which can overcome or alleviate the above defects or problems becomes a problem to be solved in the art.
