Description

Segmentation heat absorption-segmentation compression-segmentation expanding gas compression heat pump

Technical field:

The invention belongs to absorption type heat pump.

Background technology:

Gas compression formula heat pump is one of a kind of capital equipment during waste heat is used, and can bring the many-sided benefit of energy-saving and environmental protection and economic dispatch.Gas compression formula unit mainly is comprised of basic elements of character such as compressor, heater, decompressor and low temperature heat exchangers; Its heat supply mainly relies on the working medium after compression heats up to discharge sensible heat in heat exchanger and finishes heating to heated medium.In the situation that heated medium parameter (mainly being temperature) is definite, the residual heat resources amount is fewer, the variations in temperature interval of waste heat medium is then larger, the temperature of refrigerant medium after the decompressor decompressional expansion then requires lower, heat transfer temperature difference between waste heat medium and the refrigerant medium is also just larger, the compression ratio of compressor increases thereupon, and the performance index of unit descends remarkable and lower.

When being used for refrigeration, for the heat in the cooled medium is taken away, the temperature of refrigerant medium after the decompressor decompressional expansion must be lower than the minimum temperature of cooled medium; When needs are reduced to lower temperature with cooled medium by higher temperature, adopt single low temperature heat exchanger heat-obtaining to run into equally the problem that compressor compresses is larger, the unit performance index is lower.

The backward heated medium heat supply that heats up that whole Low Temperature Thermal loads are absorbed by the more refrigerant medium of decompressional expansion and compressed machine boosts, if the thermic load of higher temperature in the waste heat medium absorbed by the low refrigerant medium of decompressional expansion degree and through corresponding compressor compresses boost heat up backward heated medium heat supply, with the waste heat medium in the thermic load of lower temperature absorbed by the more refrigerant medium of decompressional expansion and through the backward heated medium heat supply that heats up of boosting of corresponding compressor compresses, then the performance index of unit is improved.Change an angle and see, this is the structure that the temperature difference reduces, the irreversible degree of diabatic process reduces of the whole thermic load transmission of waste heat medium.

Therefore, in order to improve the performance index of unit, the most basic measure is the heat transfer temperature difference will reduce Low Temperature Thermal load in the waste heat medium and be delivered in the refrigerant medium time.When the variations in temperature interval is larger, realize that unit keeps the effective measures of superior performance index to adopt exactly plural low temperature heat exchanger and corresponding compressor, decompressor to carry out segmentation heat absorption, segmentation compression and segmentation and expands at waste heat medium (cooled medium).

In addition, the compression final temperature that adopts the backheat measure can promote unit maybe can rise to the waste heat of lower temperature the level of user's needs and not affect the unit performance index; Adopt the backheat measure also to can be used for reducing compression ratio.
