Description
Technical field
The present invention relates to field of ventilation equipment.
Background technique
Now frequently with fresh air system have it is following several, unidirectional straight-line, two-way straight-line either two-way heat exchange
Formula, unidirectional straight-line, which refers to, is directly input to interior by a pipeline for outdoor air, and indoor turbid air passes through door
The discharge such as window；Two-way straight-line refers to that also one will be indoor muddy empty in addition to having one for other than the pipeline of outdoor air input
The pipeline of gas output, but two pipelines do not have crosspoint, without heat exchange；Bidirectional heat exchanging type refers to an admission line,
One exhaust pipe, two pipelines input or be discharged again after heat exchange by air inlet/outlet heat exchanger.Compared with frequently with
Be Bidirectional heat exchanging type, after heat exchange, the outdoor air inputted is more nearly room temperature.But existing heat is handed over
A kind of outdoor air for generally there was only single temperature of parallel operation access, the either heating or cooling during heat exchange,
Its efficiency is all very low.And this only by the fresh air system of air inlet/outlet heat exchange, there is also more defects: for example, in outdoor
When temperature subzero, outdoor air will appear frost after entering air inlet/outlet heat exchanger, can not normally carry out hot friendship
Program is changed, and will affect the service life of air inlet/outlet heat exchanger；It finally enters and is only to the outdoor air of conditioned space
With discharge air carried out a heat exchange, may still have a certain distance with indoor set temperature, cannot reach one compared with
Ideal temperature value.
Summary of the invention

5. the temperature control mode for the fresh air system entered the wind as claimed in claim 4 to heat exchanger dual temperature, it is characterised in that: in step
Include the following steps before rapid S1,
Outdoor air is divided into two parts and is sent into two different channels by S10, while to the air discharge in conditioned space；
S11, a portion outdoor air carry out heat exchanger with the air to conditioned space discharge by second heat exchanger
It is further continued for being delivered to first air intake duct later, another part outdoor air is fed directly to second air intake duct, thus
Obtain two kinds of different air of temperature.
6. the temperature control mode for the fresh air system entered the wind as claimed in claim 5 to heat exchanger dual temperature, it is characterised in that: in step
Include the following steps before rapid S10,
S00 extracts outdoor air, is further continued for conveying after handling via third heat exchanger.
7. the temperature control mode for the fresh air system entered the wind as claimed in claim 4 to heat exchanger dual temperature, it is characterised in that: when the
When being refrigerant in one heat exchanger, if outdoor temperature is lower than when set temperature in conditioned space, stop electric refrigeration work
Or pipeline refrigerant provides；
When in first heat exchanger being heating agent, if outdoor temperature is higher than when set temperature in conditioned space, stop electricity
Heat work or pipeline heating.
