Problems solved by technology

To increase the dehumidification capacity, the only way to reduce the evaporation temperature is to reduce the energy efficiency ratio of the system, and the air supply temperature is low, which requires a reheating process
In addition, the freon working fluid used in the refrigeration system is not conducive to environmental protection requirements

Abstract

The invention discloses an air compression type cooling and dehumidifying air-conditioning system which is composed of an air inlet space, a gas compressor, a humidity conditioning heat exchanger, a heat regenerator, dropping equipment, a moisture separator, an air-supplying space, cold and heat regulation auxiliary equipment, a pipeline and a valve. The system directly takes air as the working medium and can cool and dehumidify air in summer and heat and humidify the air in winter by switching the valve. The system adopts an open system to avoid indirect heat exchange loss of a closed cycle system and adopts the mode of multi-stage cooling and backheating to cause the system to have strong dehumidifying capacity and higher energy efficiency ratio. The system breaks through the limitation that the common refrigeration type dehumidifier only has the refrigeration function for air recycling dehumidification, and the system has the functions of cooling and dehumidifying in summer and heating and humidifying in winter. The system is applied to the dehumidification and ventilation in various places with air conditioning system and especially in underground buildings, such as underground department stores, civil defence projects and the like.

Description

technical field [0001] The invention relates to the technical field of air dehumidification and temperature adjustment, in particular to an air compression cooling and dehumidification air conditioning system. Background technique [0002] With the continuous improvement of China's urbanization level and the rapid development of the residential mode of concentrated living communities, the underground buildings constructed in combination with civil air defense projects in peacetime and wartime can bring three-dimensional comprehensive development effects to the city and can effectively use space resources. Compared with ground buildings, the biggest weakness of underground buildings is damp, especially in summer. The main reasons for its humidity are: water leakage from the surrounding and covering layers, residual water from daily maintenance, moisture inside the project, moisture from humid air, etc. Therefore, how to effectively dehumidify and reduce the energy consumptio...
