Title High water-cut crude design of heat pump system
Abstract
Our extensive use of today's society is not renewable energy sources such as coal, petroleum, natural gas, the energy use caused serious damage to our environment, but also caused a serious energy crisis, now national introduction of relevant documents, requirements vigorously develop energy-saving and emission reduction projects, and air source heat pumps is strongly supports an energy saving and environmental protection technologies.
This article introduces the working principle of air-source heat pump for heating oil, characteristic and its specific design. And its working principles, advantages and disadvantages, the results of these were introduced. Followed from the principle of heat pump and how vapor compression refrigeration cycle provides a more detailed composition of air-source heat pump and designing method of the underlying. Finally select suitable compressor, throttle devices and auxiliary equipment.
Key words: air-source heat pump design of crude oil heating
