Description

Adsorption type air water production system matched with concentrated cold source Technical Field The invention relates to an adsorption type air water production system matched with a concentrated cold source, and belongs to the technical field of air water production. Background The air water generator can prepare liquid water from air, and is suitable for indoor environment treatment and water supplementing application of building groups, industrial parks, commercial complexes and partial water source deficient areas which are available by concentrated cooling facilities. The operation working condition facing the technology is that outdoor or indoor air is treated through a unit air duct, the stable water production is required under the low-humidity or seasonal dry-cold working condition, and the energy consumption and the operation maintenance convenience are considered. The existing air water production technology mainly adopts two means of cooling dehumidification or adsorption dehumidification. Cooling and dehumidifying, namely cooling air to below the dew point by using compressor refrigeration or chilled water as a low-temperature cold source through a surface cooler or an evaporator for condensing and separating water, adsorbing and dehumidifying by using a rotating wheel for adsorbing air moisture, regenerating and desorbing water vapor by using a high-temperature heat source, and condensing in a cold section. In order to meet the low temperature required by cooling and dehumidification, a dispersion heat pump or a concentrated cold water machine room is usually adopted for cooling, and electric heating or steam heating is usually adopted for adsorption regeneration to provide high-temperature regenerated heat. Cooling dehumidification tends to frost or ice when the surface temperature of the heat exchanger is lower than the freezing point of water vapor, which results in reduced heat exchanger efficiency and frequent defrosting, and it is difficult to stably achieve deep dehumidification water production with dew points lower than about 10 ℃ or moisture contents less than about 7.0 g/kg. When the humidity of the inlet air is low or the humidity is insufficient, the inlet air is difficult or impossible to prepare water by simply relying on cooling and dehumidification. On the other hand, if the traditional adsorption rotating wheel is regenerated by adopting electric heating or steam heating, the regeneration needs to be carried out at a high temperature of 120-130 ℃, the energy consumption is high and the economical efficiency is poor, and the engineering realization problems of heat energy matching and air path coupling are faced when the heat pump is coupled with the rotating wheel to recover the condensation heat. Therefore, an adsorption type air water making system matched with a concentrated cold source is required to be designed, and the problems of difficult water making, higher energy consumption and low adsorption efficiency in the low-humidity working condition in the traditional air water making are solved.
