Abstract

The invention discloses a one-stage throttling complete cooling carbon dioxide two-stage refrigeration/heat pump integrated experiment table which consists of water systems and a coolant system, and comprises a carbon dioxide low-pressure compressor, a carbon dioxide oil separator I, a carbon dioxide intercooler, a carbon dioxide high-pressure compressor, a carbon dioxide oil separator II, a coolant stop valve group, carbon dioxide tubular heat exchangers (I and II), carbon dioxide finned tube heat exchangers (I and II), electric heaters (I and II), single air conditioners (I and II), water pumps (I and II), a first heat preservation water tank, a second heat preservation water tank, a carbon dioxide gas-liquid separator, a flowmeter group, a dry filter and the like; the switch states of corresponding coolant stop valves are operated to realize simulation of a one-stage throttling middle complete cooling two-stage transcritical carbon dioxide air-cooled refrigeration system, an air source heat pump, a water-cooled refrigeration system, an air source condensation heat recovering system, an air-cooled cold water unit system, a water source heat pump, a water-cooled cold water unit system and a water source condensation heat recovering system.

Description

technical field [0001] The invention relates to a refrigeration / heat pump experiment platform, in particular to a two-stage refrigeration / heat pump comprehensive experiment system with one-stage throttling and complete cooling of carbon dioxide. 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] Ai...
