Embodiment Construction

[0016] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0017] The purpose of the present invention is to provide a simple and efficient heat pump driven countercurrent solution humidity control fresh air unit. The heat and mass exchange between the solution and the air in the unit is in the form of countercurrent, and the evaporator and condenser of the heat pump are distributed in the solution circulation system. The lowest point and the highest point of temperature, in order to minimize the irreversible loss in the process of heat and mass exchange; the structure of the solution delivery pipeline of the unit is simple, which reduces the mixing loss between the dehumidification solution and the regeneration solution, and improves the overall effici...

Abstract

The invention relates to a reverse-flow solution desiccant fresh air handling unit driven by a heat pump. The fresh air handling unit comprises a first gas-liquid contact exchange module, and a second gas-liquid contact exchange module, wherein a solution outlet of the first gas-liquid contact exchange module is communicated with a spray device of the second gas-liquid contact exchange module through a first pipeline; a solution outlet of the second gas-liquid contact exchange module is communicated with a spray device of the first gas-liquid contact exchange module through a second pipeline; a heat pump circulation pipeline is successively connected with a first end of a compressor, a condenser, an expansion valve, an evaporator and a second ends of the compressor to form circulation; and the first pipeline performs heat exchange through the condenser, and the second pipeline performs heat exchange through the evaporator. According to the reverse-flow solution desiccant fresh air handling unit, the evaporator is used for cooling a strong solution output from an outlet of a regeneration module, and the condenser is used for heating a dilute solution output from an outlet of a dehumidification module, thus effectively using energy of heat recovery between the dehumidification module and the regeneration module, and optimizing the system efficiency.

Description

technical field [0001] The invention relates to the field of air treatment devices, in particular to a heat pump-driven countercurrent solution humidity control fresh air unit. Background technique [0002] The existing traditional air-conditioning system uses condensation and dehumidification to process air, and uses a refrigeration mechanism to extract 7 / 12°C low-temperature frozen water to lower the air temperature below the dew point temperature to achieve condensation and dehumidification of the air. This air-conditioning treatment method has the following problems: the evaporation temperature of the refrigeration unit is low, and the cooling efficiency is low; There is condensed water in the pipe, which is easy to breed bacteria. The solution humidity control method uses the salt solution with humidity control properties as the working medium, and directly contacts with the fresh air for heat and mass exchange to realize the process of air humidity adjustment. The so...
