Abstract

The invention relates to an ammonia power or refrigerating composite circulating system with an adjustable output cold power ratio. An exit solution of an ammonia power or refrigerating circulating system absorber ABS2 is divided by a shunt SP3 and one of divided solutions is pressurized by a pump P2, goes through a switch S3, is mixed with a solution of an absorption type refrigerating circulating system in a mixer M1, heated by a solution heat exchanger SHE and sent to a generator DE. A weak solution sent out from an exit of a rectifying tower REC1 in the ammonia power or refrigerating circulating system exchanges heat in a heat exchanger HE2, goes through an expansion valve V1 and is divided by a shunt SP2. One of divided solutions goes through a switch S2, is mixed with an exit solution of the generator DE of the absorption refrigerating system in a mixer MX2 and enters into an absorber ABS3. A solution of an exit of the absorber ABS3 is divided by a shunt SP4 and one of divided solutions goes through a switch S1 and enters into an absorber ABS1. Two systems operate in a coupling mode or in an isolated mode through opening and closing of the S1, the S2 and the S3.

Description

technical field

[0001] The invention relates to a medium and low temperature waste heat recycling technology, in particular to an ammonia power / refrigeration composite cycle system with adjustable output cooling power ratio. Background technique

[0002] In order to make full use of the waste heat in the exhaust of internal combustion engines, gas turbines, and fuel cells, various types of thermodynamic cycles are currently used for waste heat recovery and utilization. Vapor concentration, so work and cooling can be output simultaneously. However, the adjustment ability of the output cooling power ratio of this type of cycle is poor. In a distributed energy supply system, loads such as power cooling required by users are often changing in different seasons and at different times, which requires the distributed energy supply system to have good load regulation capabilities.
