Direct Expansion Heat Recovery Method and Device

摘要

A direct expansion heat recovery method includes a complete refrigeration cycle including a compression process by a compressor, a condensing process by a condenser, a throttling process by an expansion valve, and an evaporation process by an evaporator. A heat output process of a condensing process of the condenser includes providing at least two condensers which are connected serially. A heat output required by a second condenser is to proportionally control a heat output of a first condenser, so as to precisely control the heat output required by the second condenser. A heat input process of an evaporation process of the evaporator includes providing at least two evaporators which are connected serially. A heat input required by a second evaporator is to proportionally control a heat input of a first evaporator, so as to precisely control the heat input required by the second evaporator.

1. A direct expansion heat recovery method comprising:
a complete refrigeration cycle including a compression process by a compressor, a condensing process by a condenser, a throttling process by an expansion valve, and an evaporation process by an evaporator; the improvement comprising: a heat output process of a condensing process of the condenser includes providing at least two condensers which are connected serially; a heat output required by a second condenser is to proportionally control a heat output of a first condenser, so as to precisely control the heat output required by the second condenser; and the second condenser functions as a heater or humidifier of heat recovery, without affecting a normal operation of the compressor.
