Abstract

The invention relates to the technical field of heat exchange, in particular to a multi-stage series displacement heat exchange system. It includes an evaporator, a compressor, a condenser, and a first throttling member connected through a working fluid channel; the outlet of the evaporator is connected to the inlet of the compressor, and the outlet of the compressor is connected to the condenser Inlet, the outlet of the condenser is connected to the inlet of the first throttle, and the outlet of the first throttle is connected to the inlet of the evaporator; it is characterized in that: the outlet of the condenser and the first A multi-stage series heat exchange area is arranged between the inlets of the throttling element. The multi-stage series heat replacement area established between the condenser and the first throttling member isolates the condensation area and the evaporation area of ​​the system, and at the same time enhances condensation, isolates the influence of condensation waste heat on the evaporation area, making the system Energy efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a multi-stage series displacement heat exchange system. Background technique [0002] Such as figure 1 , traditional air conditioning and heat pump heating / refrigeration systems include compressors, condensers, throttling parts, and evaporators. Compressed gas with high temperature and high pressure flows through the condenser to release heat, and finally enters the evaporator after being depressurized by the throttle. The working medium continuously absorbs and releases heat during the circulation process in the system to realize system heating / cooling. [0003] When the heating / refrigerating system is used for heating, the condenser is installed in the environment that needs to be heated, and the working fluid absorbs the heat in the environment where the evaporator is located in the evaporator, and is transported to the condenser through the working medium flow channel...
