Tube-plate evaporative condensing air-conditioning unit with packing

Abstract

The invention provides a tube-plate evaporative condensing air-conditioning unit with packing. The unit comprises an evaporation and air supply unit and a compression and condensing unit. The evaporation and air supply unit consists of a drying and filtering device, an expansion valve, an evaporator and a centrifugal fan which are sequentially connected, and the compression and condensing unit isformed by connecting a compressor and a condenser; the condenser is connected with the drying and filtering device, and the compressor is connected with the evaporator; the air-conditioning unit is provided with a condensate recovery system which is formed by connecting a condensate recovering collector of the evaporator with the condenser by a tube or a water pump; and an indoor air supply system of the evaporation and air supply unit consists of an outdoor fresh air inlet of the evaporator, a unit air supply outlet and the centrifugal fan, or consists of the outdoor fresh air inlet of the evaporator, a unit return air inlet, the unit air supply outlet and the centrifugal fan. The tube-plate evaporative condensing air-conditioning unit has high heat exchange efficiency, and can realize maximal energy recovery and reduction of energy consumption and water consumption, effectively solves increased energy consumption resulting from increased fresh air volume of an air-conditioning system and realizes double performance of saving energy and water and health care.

Description

technical field [0001] The invention relates to air-conditioning and refrigeration equipment, in particular to a plate-tube evaporative condensing air-conditioning unit with packing. Background technique [0002] As the global temperature rises, the popularity of air conditioners is increasing day by day. Especially in my country, the air conditioner industry has developed rapidly in the past ten years, but the popularity of air conditioners has brought enormous pressure to the already tight power supply facilities. According to statistics, taking an office building as an example, the electricity consumption of air conditioners accounts for 35% of the total electricity consumption of the whole building. It can be seen that the operating cost of an air conditioner is huge. Sometimes, in the hot summer, due to the shortage of power supply, the air conditioner may even fail to operate. It can be seen that the development of energy-saving air-conditioning equipment has become th...

Problems solved by technology

In order to reduce the total load, the method of reducing the supplementary amount of fresh air is often adopted, which will easily cause the air quality in the air-conditioned area to be poor and fail to meet the hygienic requirements

At the same time, in order to ensure normal indoor air pressure, part of the air is often discharged directly, and the temperature of the discharged air is low, only about 28 degrees, which is a good source of cooling air with low temperature and low humidity, but because the current equipment cannot use this part of energy directly caused waste

In addition, the existing air-conditioning cabinets will generate a large amount of condensed water during the cooling process. The existing technology is to directly drain the generated condensed water. Since the temperature of the condensed water is only about 10-15°C, the cooling capacity Big loss

[0005] For the transition season, the indoor temperature is generally higher than the outdoor temperature, and the fresh air can be used to bear the indoor cooling load, that is, the air conditioning system is not turned on, only the ventilation system is turned on, and the fresh air with a lower temperature outside is introduced to exchange heat with the indoor air. , to lower the temperature and adjust the indoor air quality. At this time, if the traditional refrigeration unit is used, another set of ventilation equipment is required, and the investment is increased.
