Heat source tower solution concentration device based on lubricating oil of screw compressor

Abstract

The invention discloses a heat source tower solution concentration device based on screw compressor lubricating oil. The heat source tower solution concentration device based on the screw compressor lubricating oil comprises a sealed container, wherein an isolation plate is arranged in the sealed container; a finned tube heat exchanger is arranged on one side of the isolation plate, and the other side of the isolation plate is a solution side; the bottom of the finned tube heat exchanger is connected with a solution in a heat source tower through a first valve, and the top of the finned tube heat exchanger is connected with the first inlet end of a heat exchanger through a water pump A; a liquid divider connected with the first outlet end of the heat exchanger is arranged on the solution side of the sealed container; the bottom of the solution side is connected with a heat pump system of the heat source tower through a second valve and a water pump C; the second inlet end of the heat exchanger is connected with lubricating oil of a screw compressor so as to heat the solution in the heat source tower; the temperature of the lubricating oil is higher than that of the solution in the heat source tower; therefore, the heat required for concentration of the solution in the heat source tower is greatly reduced, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to a heat source tower solution concentration device based on screw compressor lubricating oil, in particular to a high-efficiency heat source tower solution concentration device suitable for heat utilization of screw compressor lubricating oil in building energy saving. Background technique [0002] Air conditioners are major building energy consumers. How to effectively reduce air conditioner energy consumption and improve energy utilization efficiency is the focus of research in the air conditioner industry. my country's hot-summer and cold-winter regions along the Yangtze River Basin are characterized by hot summers, cold and humid winters, and relatively high air humidity. At present, there are mainly three traditional ways of cooling / heating (" / " means "or") in this area: water-cooled chiller + boiler, water / ground source heat pump and air-cooled heat pump. [0003] Among them, the air-cooled heat pump can realize cooling / h...

Problems solved by technology

However, due to the climate characteristics of hot summer and cold winter regions, it is inevitable that the solution absorbs moisture from the air during the heat exchange process of the heat source tower solution from the air.
