Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Illustrate the energy-saving combined type of independent temperature-humidity control described in the utility model below in conjunction with specific embodiment
Air-conditioner set.
As shown in Figure 1, above-mentioned energy-saving unitary air handling unit include just effect fresh air section 1, maintenance section, fresh air surface cooling section 2,
Just effect air return section 3, return air surface cooling section 4, humidifier section 5, blower section 6, flow equalization section 7, wind outlet section 8, above-mentioned just effect fresh air section 1, inspection
Repair section, fresh air surface cooling section 2 sets gradually composition fresh air channel, include front and back be connected with the return air channel that fresh air channel is set up in parallel
First effect air return section 3 and return air surface cooling section 4, just imitate and bypass Electric air valve 9 be installed between fresh air section 1 and just effect air return section 3, newly
The outlet of wind surface cooling section 2 and return air surface cooling section 4 is connected with the import of humidifier section 5 respectively, humidifier section 5 and blower section 6, flow equalization section
7 and wind outlet section 8 be sequentially connected.The mixed humidity of fresh air, return air is adjusted in humidifier section 5, ensures necessary humidity of blowing, makes room
The humidity of interior air is maintained in required humidity range.
Specifically, electronic air inlet valve 1.2 just is installed at the fresh inlet 1.1 of effect fresh air section 1, is equipped in shell antifreeze
Electric heater 1.3, first filter 1.4, maintenance lamp；Maintenance section is equipped with maintenance door, maintenance lamp；Installation in fresh air surface cooling section 2
There is the first surface cooler 2.1；Electronic air returning valve 3.2 just is installed at the return air inlet 3.1 of effect air return section 3, inspection is installed in shell
Repair door, maintenance lamp；Second surface cooler 4.1 is installed in return air surface cooling section 4；Humidifier section 5 is equipped with maintenance door, is mounted therein with and adds
Wet device 5.1 and maintenance lamp；Blower section 6 is equipped with maintenance door, is mounted therein with pressure fan 6.1 and maintenance lamp；Flow equalization section 7 is pacified
Equipped with maintenance door, maintenance lamp；Electronic outlet valve 8.2 is installed at the air outlet 8.1 of wind outlet section 8, maintenance is installed on shell
, medium effeciency filter 8.3 and maintenance lamp are installed in shell.In addition, check whether filter blocks for convenience, it is new in first effect
It is provided with the first differential manometer 10 between wind section 1 and fresh air surface cooling section 2, just imitates and is provided with the between air return section 3 and return air surface cooling section 4
Two differential manometers 11, are provided with third differential manometer 12 between flow equalization section 7 and wind outlet section 8.
In use, fully closed bypass Electric air valve 9, make fresh air, return air respectively in fresh air channel and return air channel individually into
After row primarily efficient filter and table cold treatment, it is incorporated to humidifier section 5, is then sent into room through blower section 6, flow equalization section 7 and wind outlet section 8 successively
It is interior.
Air handling process is generally three kinds following：
The first, fresh air is processed to the thermoisopleth of indoor design condition point, and fresh air only undertakes fresh air sensible heat load, surface cooler
Chilled water supply water temperature is 14 DEG C, and return water temperature is 19 DEG C；Return air undertakes whole humidity loads and indoor sensible heat load, and surface cooler is cold
It is 7 DEG C to freeze water supply water temperature, and return water temperature is 12 DEG C.Therefore, returning for returned air cooler low-temperature receiver can be used in fresh air cooler low-temperature receiver
Water or common high temperature cold water unit two schemes.
Second, fresh air be processed to indoor design condition point etc. wet line, fresh air undertake fresh air sensible heat refrigeration duty, fresh air latent heat
Load, the indoor sensible heat load in part, surface cooler chilled water supply and return water temperature take 7/12 DEG C；Return air undertake indoor latent heat refrigeration duty,
The indoor sensible heat refrigeration duty in part, surface cooler chilled water supply and return water temperature take 7/12 DEG C.At this point, the surface cooler of fresh air, return air
Using chiller unit as low-temperature receiver.
Second, fresh air be processed to less than indoor design condition point etc. wet line, fresh air undertake fresh air sensible heat refrigeration duty, fresh air
Latent heat load, indoor latent heat load, the indoor sensible heat load in part, surface cooler chilled water supply and return water temperature take 7/12 DEG C；Return air is not
It undertakes humidity load, undertake part interior sensible heat load, surface cooler chilled water supply and return water temperature takes 14/19 DEG C.At this point, fresh air, return
The surface cooler of wind uses chiller unit and high temperature cold water unit as low-temperature receiver respectively.
Alternatively, fully closed bypass Electric air valve 9 can also be partially opened, and according to the wind pushing temperature of air-conditioning setting, humidity
Its aperture is adjusted, fresh air+part return air, remaining return air is made individually to carry out primarily efficient filter in fresh air channel and return air channel respectively
After table cold treatment, it is incorporated to humidifier section 5, is then sent into interior through blower section 6, flow equalization section 7 and wind outlet section 8 successively.
As it can be seen that the utility model realizes the independent control of air-conditioning humiture, since surface cooler can reasonably select
Using common high temperature cold water unit, chiller unit or returned air cooler low-temperature receiver return water as low-temperature receiver, therefore, it is possible to abundant
Using thermal energy, the shortcomings of overcoming excessive conventional ASSEMBLE air-conditioner set supply air temperature difference, waste of energy.
