Evaporative cooling type water chilling unit system and air conditioner

Abstract

The invention discloses an evaporative cooling type water chilling unit system and an air conditioner, and belongs to the field of air conditioners. The evaporative cooling type water chilling unit system comprises a compressor, an evaporative condenser, a drying filter, an energy saving device, a falling film evaporator and a control system, wherein an exhaust opening of the compressor communicates with an inlet of the evaporative condenser through a first pipeline; an outlet of the evaporative condenser communicates with an inlet of the drying filter through a second pipeline and further communicates with a cooling inlet of the compressor through a sixth pipeline; an outlet of the drying filter communicates with an inlet of a main liquid pipe of the energy saving device through a third pipeline, an outlet of the main liquid pipe of the energy saving device communicates with an inlet of the falling film evaporator through a fourth pipeline, an outlet of the falling film evaporator communicates with an inlet of the compressor through a fifth pipeline, an exhaust outlet of the energy saving device communicates with the inlet of the compressor through an eighth pipeline, and the compressor is electrically connected with the control system. According to the scheme, the evaporative cooling type water chilling unit system and the air conditioner are good in heat transfer performance, high in evaporating intensity, free of rising of the boiling point caused by a static pressure head and high in heat exchange efficiency.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an evaporative cooling chiller system and an air conditioner. Background technique [0002] With the development of economy and the continuous improvement of human living standards, the application of air conditioners is becoming more and more popular. While air-conditioning adapts to economic development and meets human needs, it also brings huge energy consumption burdens and other negative effects such as the greenhouse effect to humans. Therefore, reducing energy consumption of air-conditioning and seeking a sustainable development path for air-conditioning Become an important and primary problem faced by air-conditioning design. At the same time, the new mandatory national standards of "Energy Efficiency Limits and Energy Efficiency Levels for Chillers" and "Energy Efficiency Limits and Energy Efficiency Levels for Water (Ground) Source Heat Pump Units" have been p...

AI Technical Summary

Problems solved by technology

[0003] At present, the heat exchange heat exchanger of the evaporative condenser used in the evaporative and condensing integrated chiller adopts the traditional circular coil. The effective heat exchange area of ​​the condenser is small, the heat exchange area is large, the heat transfer coefficient is small, and the overall size of the unit is large. , the heat exchanger of the condenser is easy to form dry spots, easy to scale, and consumes a lot of energy

[0004] The traditional evaporator adopts flooded evaporator, which has poor heat transfer effect, lower evaporation temperature, large amount of refrigerant injection, and poor heat transfer stability of the system
