Two-stage throttling incomplete cooling carbon dioxide refrigeration/heat pump comprehensive experimental table

Abstract

The invention discloses a two-stage throttling incomplete cooling carbon dioxide refrigeration / heat pump comprehensive experimental table. The comprehensive experimental table comprises water systems and a refrigerant system, and particularly comprises a carbon dioxide low-pressure compressor, a carbon dioxide oil separator I, carbon dioxide gas-liquid separators I and II, a carbon dioxide high-pressure compressor, a carbon dioxide oil separator II, a refrigerant stop valve group, carbon dioxide shell-and-tube heat exchangers I and II, carbon dioxide finned tube exchangers I and II, electric heaters I and II, simplex air conditioners I and II, water pumps I and II, a first heat preservation water tank, a second heat preservation water tank, a flowmeter group, a dry filter, and the like. An air cooling refrigerating system, an air source heat pump, a water cooling refrigerating system, an air source condensation heat recovery system, an air cooling water chiller unit system, a water source heat pump, a water cooling water chiller unit system and a water source condensation heat recovery system which adopt a two-stage transcritical carbon dioxide form of two-stage throttling incomplete inter-cooling can be simulated through adjusting the on-off states of the corresponding refrigerant stop valves.

Description

technical field [0001] The invention relates to a heat pump system, in particular to a two-stage throttling incomplete cooling carbon dioxide refrigeration / heat pump comprehensive experiment platform. Background technique [0002] At present, most of the two-stage transcritical carbon dioxide experimental systems used in colleges and universities are simple heat pump systems, which have relatively single functions and low equipment utilization, which has caused a huge waste of resources invisibly; at the same time, scattered and single-function The test bench will occupy a large laboratory area; colleges and universities urgently need to integrate heat pump systems with single functions to reduce the floor area, improve the utilization rate of equipment, reduce the waste of the school in experiments, and improve the comprehensiveness of the school's experimental equipment. utilization rate. Contents of the invention [0003] Aiming at the above-mentioned prior art, the pr...
