Described recuperation of heat intensification air intake/outtake system, wherein in system, pipeline external is provided with heat-insulation layer.
The described wherein said water circulating pump of recuperation of heat intensification air intake/outtake system is provided with switch.
It should be noted that, medium in the described wherein said radiator of recuperation of heat intensification air intake/outtake system is the liquid that freezing point is less than-10 ℃, preferred described medium is that freezing point is below-20 ℃, boiling point is at more than 100 degrees Celsius anti-icing fluid, and further preferred described medium is ethylene glycol, glycerine or lubricating oil.The selection of medium does not have specific (special) requirements, is medium conventional in the heat pump of this area, as long as it is low temperature resistant, heat transfer efficiency is high, selects such medium to make the utility model can not be subject in outdoor normal use in winter the impact of low temperature.The utility model can for example can select freezing point to be below-20 ℃ according to the corresponding medium of specific geographic environmental selection in the north, can select freezing point below-10 ℃ in south.
Described heat-insulation layer can be selected from the conventional insulation material in this area and form, and concrete thickness also can carry out choose reasonable according to actual needs, its objective is in order to guarantee that heat can not be dispersed in surrounding environment in winter, thereby increases operation rate.
Compared with prior art, because recuperation of heat intensification air intake/outtake system of the present utility model arrives fresh wind port by radiator by the transfer of heat of exhaust outlet, the fresh air temperature that makes to enter in kitchen is improved, thereby in winter, improved the temperature in kitchen, and be provided with cooking fume remover, can effectively the oil smoke in Exhaust Gas be removed to absorption, avoid whole oil smoke to pollute for whole system, be convenient to clean.And in radiator, adopt the low temperature resistant liquid such as anti-icing fluid as medium, can be effectively in outdoor use in winter.Simultaneously in system of the present utility model, adopt heat pump switch to control, whether can select voluntarily the transfer of heat of Exhaust Gas, thereby be applicable to this system, in summer or indoor temperature, select not shift the heat in Exhaust Gas when overheated.The utility model also arranges heat-insulation layer by the pipeline external in system, effectively prevents energy loss, makes full use of remaining heat energy and plays a role in energy saving.
