The invention discloses a refrigerating device, in particular to a heating power type piston compressor low boiling point working medium refrigerating device, which is formed by a piston type heating power pressure turbine. Two steam inlets of a power cylinder of the piston type heating power pressure turbine are connected with a heater through pipelines, two steam inlets of a compressing cylinder are connected with an evaporator through pipelines, and four steam outlets of the power cylinder and the compressing cylinder are connected with a condenser through pipelines. The refrigerating device recycles low-pressure steam, uses high-pressure low boiling point working medium steam to compress low-pressure low boiling point working medium steam, and enables pressure and temperature of the low-pressure steam of refrigerating fluid in the evaporator to be increased, so that quantity of heat exchanged out by refrigeration is conveniently discharged in atmosphere, and the refrigeration efficiency is greatly improved.
Description
technical field [0001] The invention relates to a refrigeration device, in particular to a low-boiling-point refrigerant refrigeration device for a thermal piston compressor. technical background [0002] At present, industrial production produces a large amount of low-temperature waste heat, including steam at about 100°C, hot water at 80-90°C, and waste heat of flue gas at about 100°C. These waste heat are not easy to use and are discharged. In order to utilize low-temperature waste heat refrigeration technology, it includes steam injection refrigeration, low boiling point working medium steam injection refrigeration and lithium bromide absorption refrigeration. Steam injection refrigeration has not been widely used due to its low efficiency, and low-temperature lithium bromide refrigeration has not been widely promoted due to its large investment. The main reason for the low efficiency of steam injection refrigeration is the low efficiency of the steam ejector, which ma...
