A kind of enthalpy-increasing device for being applied to low-temperature heating
Technical field
Specifically a kind of enthalpy-increasing device for being applied to low-temperature heating of this utility model.
Background technology
Heating machine set is run at low ambient temperatures, it may appear that excessive discharge temperature phenomenon, affects the efficiency of water heating, mainly
It is because that return-air amount is reduced, causes compression ratio to increase, caused by motor temperature rise is high, to using brings many potential safety hazards.
Utility model content
The purpose of this utility model is to solve above-mentioned deficiency, there is provided a kind of enthalpy-increasing device for being applied to low-temperature heating.
The purpose of this utility model is achieved through the following technical solutions:
A kind of enthalpy-increasing device for being applied to low-temperature heating, including air inlet, gas outlet, increasing enthalpy device entrance, increasing enthalpy device outlet,
Evaporator body and increasing enthalpy device pipeline;Air inlet is provided with the top of evaporator body, bottom is provided with gas outlet, increasing enthalpy device pipe
Road is arranged on gas outlet top, and one end of increasing enthalpy device pipeline is provided with increasing enthalpy device entrance, and the other end of increasing enthalpy device pipeline is provided with
Increasing enthalpy device is exported.
Further, the increasing enthalpy device pipeline is rugosity.
Further, the evaporator body is carbon steel inner lining structure.
Further, described increasing enthalpy device pipeline is welding with the connected mode of evaporator body.
Further, described air inlet and gas outlet are all the top and bottom for being welded on evaporator body.
From the above-mentioned description to this utility model structure, compared to the prior art, this utility model has following excellent
Point:
This utility model is reasonable in design, easy to use, increases return-air amount, reduces compression ratio, and delivery temperature is reduced, system pressure
Power declines, and has good application prospect.

Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only to explain
This utility model, is not used to limit this utility model.
Embodiment 1
Below in conjunction with the accompanying drawings this utility model is further described:
As shown in figure 1, a kind of enthalpy-increasing device for being applied to low-temperature heating, including air inlet 1, gas outlet 2, increasing enthalpy device entrance
3rd, the outlet 4, evaporator body 5 of increasing enthalpy device and increasing enthalpy device pipeline 6, the top of evaporator body 5 are provided with air inlet 1, and bottom sets
Gas outlet 2 is equipped with, increasing enthalpy device pipeline 6 is arranged on 2 top of gas outlet, and one end of increasing enthalpy device pipeline 6 is provided with increasing enthalpy device entrance 3,
The other end of increasing enthalpy device pipeline 6 is provided with increasing enthalpy device outlet 4.
Further, the increasing enthalpy device pipeline is rugosity.
Further, the evaporator body is carbon steel inner lining structure.
Further, described increasing enthalpy device pipeline is welding with the connected mode of evaporator body.
Further, described air inlet and gas outlet are all the top and bottom for being welded on evaporator body.
This utility model arranges increasing enthalpy device in evaporator outlet, exports the coolant absorptive condenser of evaporator outlet low temperature
The coolant heat of middle temperature, realizes that double evaporation-cooling heats up, reaches the purpose of increasing enthalpy.The coolant of condensator outlet realizes supercooled liquid simultaneously
Change, contribute to evaporation of the coolant after throttling.
Preferred embodiment of the present utility model is the foregoing is only, it is not to limit this utility model, all at this
Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in this utility model
Protection domain within.
