technical field

The utility model relates to a system combining condensed water recovery and exhaust air cooling and heat recovery.

Background technique

With regard to the current exhaust system of buildings, the exhaust openings are arranged on the roof or the facade, and due to various factors such as appearance and size, it is often impossible to install hoods. As a result, the exhaust port may be exposed to the positive pressure area of natural wind, resulting in problems such as poor exhaust air or even reverse irrigation, which is not conducive to the discharge of indoor dirty air. Moreover, the indoor air discharged by the exhaust system is lower than the outdoor air temperature in summer and higher than the outdoor air temperature in winter, which has a certain value of cold and heat recovery.

Regarding the current recycling of condensed water from air conditioners, air conditioners will generate a certain amount of condensed water in the cooling season. At present, most of the condensed water of split-type household air conditioners is discharged to the outside at will, which will cause, for example, erosion of walls, causing noise, and causing neighbors. Disputes, breeding moss and many other problems. Generally speaking, a 1.5-horsepower household air conditioner can produce 0.4-0.7L of condensed water per hour, depending on the humidity in different regions, but in general, the recoverable amount of condensed water is considerable. For the discharge of condensed water, sometimes it is necessary to set up a special condensed water pipe, which brings unnecessary trouble to the construction. And if it can be directly introduced into the outdoor unit of the air conditioner for use, it will not only solve the troubles caused by the discharge of condensed water in life, but also turn waste into treasure and improve the heat exchange efficiency of the outdoor unit of the air conditioner.

The system of the utility model combines the utilization of condensed water and the heat recovery of exhaust air. Various outdoor air conditioning systems are mainly composed of fans and heat exchange coils, and the efficiency of heat exchange coils is directly related to the temperature of the incoming air. The lower the temperature of the incoming air in summer, the higher the efficiency of the heat exchange equipment; in winter, increasing the temperature of the incoming air can avoid or reduce the frosting problem of the heat exchange equipment. In the cooling season, the indoor air is directly used as the air intake source of the outdoor unit, and then the condensed water after atomization is blown through, so that it evaporates and takes away the heat, thereby further reducing the temperature of the air entering the cooling device of the outdoor unit. The two effects are similar. The combination can effectively improve the heat exchange efficiency of the outdoor unit of the air conditioner. Although there is no condensed water in the heating season, the indoor exhaust air as the air intake source can still improve the heat exchange efficiency of the outdoor unit under heating conditions, and can also play a certain role in protecting the outdoor unit.
