The pattern in two air passages is also used, can significantly reduce unit volume, and meet the requirement of indoor location.
There is humiture independent treating air-conditioning system, made in heretofore described Fresh air handling units using salting liquid
The humidity load of fresh air is handled for medium, whole wet bear need not be undertaken with compared to conventional Fresh air handling units evaporator
Lotus, so the evaporating temperature in evaporator can improve, the raising of evaporating temperature can greatly reduce the energy consumption of heat pump system, institute
It can be reduced very much with the energy consumption of whole unit.
Flexible system model switching mode, energy-saving effect are obvious.The present invention can be according to seasonal variations and processing fresh air
Hot humidity load proportion adjustment operational mode (total heat recovery pattern and dehumidification mode), this point is general to use mechanical refrigeration
Not available for the conventional Fresh air handling units of dehumidifying.
The present invention can also realize the energy regenerating of air-conditioned room return air in limited volume structure, when with total heat recovery
During mode operation, whole unit is in energy saver mode, and this energy recuperation mode is conventional household fresh air fan group does not have
Standby.
The present invention is particularly evident compared to the energy consumption reduction of traditional Fresh air handing unit under the wet weathers such as rainy days.Tradition
Fresh air handling units need the low-temperature receiver using lower temperature when handling big humidity load, and the refrigeration requirement in evaporator is especially big.
And when being run based on unit of the invention with dehumidification mode, the humidity load in fresh air is mainly undertaken by solution, and after moisture absorption
Weak solution can also utilize the condensation hot recycling of heat pump, so whole unit not only reduces the energy consumption of evaporator and make use of
Condensation heat, energy conservation characteristic are further embodied.
A mixed wind section is additionally provided with before the air outlet in Fresh air handing air passage of the present invention, the effect for mixing wind section is to utilize back
Wind reduces the temperature of air-supply.This set saves fresh air reheat machine compared to traditional Fresh air handling units, is reducing
The manufacture cost of unit is saved while energy consumption.
