Economic benefit analysis of lithium bromide absorption refrigeration units applied to cogeneration plants

In order to compare the performance of electricdriven compression type refrigerating machine and steamdriven lithium bromide absorption machine，defines a modified performance coefficient—equivalent performance coefficient based on the analysis of existing indices for electricdriven compression type refrigerating machines.With an example，analyses the economic benefit of applying lithium bromide absorption refrigerating machine to cogeneration plant.The results show that it can save electricity.
