Problems solved by technology

However, the condensation waste heat carried by the working fluid in the second link reduces the temperature difference between the working fluid in the evaporator and the external environment, destroying the evaporation scene of the evaporator
Therefore, in the traditional air-conditioning heat pump refrigeration / heating system, the condensation area and the evaporation area are not completely independent and isolated. The mutual infection of the districts, the energy efficiency of the whole system cannot be optimal

Abstract

The invention relates to the technical field of heat exchange, in particular to a multi-stage parallel 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 parallel heat displacement zone is provided between the inlets of the throttling element. The multi-stage parallel 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 present invention relates to the technical field of heat exchange, in particular to a multi-stage parallel replacement heat exchange system. Background technique [0002] Such as figure 1 Traditional air conditioning and heat pump heating / refrigeration systems include compressors, condensers, throttles, and evaporators. The low-temperature and low-pressure working fluid in the heating / cooling system flows through the evaporator to absorb heat and vaporize, and is Compressed into high-temperature and high-pressure gas, it flows through the condenser to release heat, and finally enters the evaporator again after being depressurized by the throttle. The working fluid continuously absorbs and releases heat during the cycle of the system to realize heating / cooling of the system. [0003] When the heating / refrigeration system is used for heating, the condenser is installed in the environment where heating is required. The working fluid absorbs the heat in the ...
