Double-cold-source device combining air cooling compression refrigeration and evaporation refrigeration

Abstract

The invention discloses a double-cold-source device combining air cooling compression refrigeration and evaporation refrigeration. A first outdoor unit heat exchanger of an exhaust fan is installed onan exhaust opening, a refrigerant outlet of the first outdoor unit heat exchanger is sequentially connected with a throttle valve, a first indoor unit heat exchanger and a first compressor through pipelines, and a refrigerant outlet of the first compressor is connected with an inlet of the first outdoor unit heat exchanger through a pipeline to form an air cooling compression refrigeration unit.A direct evaporation cooling device is arranged on the air inlet side of the first outdoor unit heat exchanger, a water outlet pipe of the direct evaporation cooling device is connected with a first user through a first water pump, and a return pipe of the first user is connected with a water distribution device positioned above the direct evaporation cooling device. The double-cold-source devicehas a reasonable structure, the air cooling compression refrigeration and the dry air energy evaporation refrigeration are combined to cool to a high-temperature terminal and a low-temperature terminal, the operation energy consumption of a whole air conditioning system is reduced, the energy efficiency ratio of the air cooling compression refrigeration is improved, and the installed power of theunit is reduced.

Description

technical field [0001] The invention belongs to air treatment equipment in the field of HVAC, in particular to a dual cold source device combining air-cooled compression refrigeration and evaporative refrigeration. Background technique [0002] With the development of air-conditioning technology, the development of multi-connected air conditioners is relatively rapid. Compared with traditional air conditioners, multi-connected air conditioners have significant advantages: using a new concept, integrating one-drag multi-technology, intelligent control technology, multiple health technologies, energy-saving technologies and network Control technology and other high-tech are integrated to meet the requirements of consumers for comfort and convenience; and the installation is convenient and beautiful, and the control is flexible and convenient. However, the energy efficiency of multi-connected units is low, the energy consumption is high, and it will dehumidify when used in dry ...

AI Technical Summary

Problems solved by technology

However, the energy efficiency of multi-connected units is low, the energy consumption is high, and it will dehumidify when used in dry and semi-dry areas, resulting in relatively dry air-conditioned areas and poor human comfort; in addition, when using multi-connected units, an additional fresh air system is required to meet the requirements. The fresh air volume required by the human body, considering the energy consumption of the entire air conditioning system, the fresh air volume designed for the fresh air system is relatively small
