The wine cellar constant temperature and humidity air conditioner is a new type of cooling equipment, which can help the wine cellar to maintain the appropriate temperature and humidity. The equipment is made of advanced technology and has the advantages of simple structure and convenient use.
The machine can help wine cellars accurately control temperature and humidity, so that red wine, white wine and other wines can be stored longer. The following Xiaobian according to 70 Pingde cave transformed into a wine cellar example to select a constant temperature and humidity air conditioner!
First, the introduction of wine cellar
Cave area: 70m2
Cave height: 2 meters
Two, the wine cellar to meet the requirements
Required humidity: 50-60%(the best storage humidity of red wine)
Required temperature: 12-17℃(the best storage temperature for red wine)
Third, equipment technical scheme
Irregular inside the cave, there are many forks, so that the temperature and humidity in various places of the cave are maintained in the red wine storage required temperature and humidity must be used air conditioning duct to maintain the balance of temperature and humidity in the cave.
The cave space is relatively low, it is necessary to use a hanging wine cellar constant temperature and humidity machine hoisted on the roof of the cave, and then use the air supply pipe and return air pipe to circulate the air in the cave.
In general, the moisture in the cave is relatively heavy, and the moisture volatilization is relatively large. In order not to affect the indoor constant temperature and humidity, the fresh air volume can not be designed too large. The volume of the cave is about 150m3. It is recommended to design two air changes, that is, the fresh air volume is 300m3/h.
Calculate the air conditioning cooling capacity required for fresh air to complete cooling and dehumidification:
To extreme weather temperature 35℃, humidity 80%RH as the new wind working standard.
According to the enthalpy and humidity chart, when the temperature is 35℃ and the humidity is 80%, the enthalpy value is 109.49kj/kg and the density is 1.13kg/m3.
When the temperature is 15℃ and the humidity is 55%, the enthalpy of dry air is 29.84kj/kg and the density is 1.22kg/m3.
300 x (1.13 29.84 x 109.49 x 1.22) present 3600 = 7.28 kw
Calculate the amount of air conditioning needed to complete the cooling and dehumidification of the cave itself:
Red wine cellar to reach 15 ° C, at least according to 300w/m2 to calculate the required air conditioning cold capacity
70×300w=21kw;
Calculate the total amount of air conditioning needed in the cave:
7.28+21=28.82kw.
Fourth, equipment selection
According to the calculation scheme, the selection of the result needs to leave a margin, and an air-cooled wine cellar constant temperature and humidity machine with the model HF30(cooling capacity is 30.5kw) should be selected.
Five, about the air duct
The height of the cave is relatively low, so the thickness of the air pipe can not be too thick, it is recommended to set the thickness of 200mm, the width of the return air pipe is 1000mm, and the width of the air supply pipe is 800mm.
The fresh air pipe can be directly connected to the return air pipe, the size of the fresh air pipe is φ120mm, the fresh air pipe can use a plastic hose, and a fresh air valve needs to be installed on the fresh air pipe to adjust the air volume.
