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

A heat exchange system, comprising 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 connected to the inlet of the condenser, the outlet of the condenser is connected to the inlet of the first throttling member, and the outlet of the first throttling member is connected to the inlet of the evaporator; it is characterized in that: the condenser A heat replacement zone is provided between the outlet and the inlet of the first restrictor. The heat replacement area established between the condenser and the first throttling member isolates the condensation area and the evaporation area of ​​the system, while improving condensation, it also isolates the influence of condensation waste heat on the evaporation area, so that the energy efficiency of the system is greatly improved .

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat exchange system. Background technique [0002] like 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 The heat is released in the air t...
