The ceiling air conditioning system based on radiation heat exchange can greatly improve the defects, but water vapor in the air can be condensed on the surface of the ceiling during the cooling process because the surface temperature of the ceiling is generally lower than the dew point temperature of the air. And the water drop that drips will influence the comfort of living environment, can also influence the refrigeration effect simultaneously, if do not get rid of for a long time, can breed the bacterium and accelerate roof corruption more. Therefore, it is important to develop a ceiling structure that prevents dripping from the top surface without affecting the cooling effect.
At present, the refrigeration furred ceiling system of general use needs to add a set of replacement ventilation system in addition, through the humiture of control air inlet, makes its dew point temperature be less than furred ceiling surface temperature and avoids the dewfall, has caused very big restriction to furred ceiling system volume like this, and applicable environment has not only the structure is complicated and the effect is not good. Meanwhile, people continuously improve the cooling ceiling plate, such as a modular water source radiation cooling ceiling plate with a ventilation terminal disclosed in application numbers CN00243552, CN00120766 and CN002435543, and the cooling effect is improved and condensation is avoided through modular cooling and air duct organization, but when the cooling ceiling plate is applied to a high-temperature and high-humidity environment, the condensation and dripping phenomenon is unavoidable and is not solved by related methods; the outdoor air is processed into low-temperature low-humidity air through air conditioning air processing equipment, heat exchange is carried out through the space above the ceiling plate, super hydrophilic materials are adopted for preventing dew condensation on the ceiling plate, but moisture vapor in the wet air forms a water film on a ceiling, and a water draining measure is lacked, so that dew condensation phenomenon cannot be effectively avoided, the life quality of a user is influenced, the air conditioning air processing equipment is needed, so that the power consumption is larger, unlike the water source radiation refrigeration energy conservation, the radiation refrigeration system brief analysis (Chen.

In this embodiment, the object is a room in the high temperature and high humidity environment of Guangzhou city, and the size is 8mx6mx3m (length×width×height). The cold water pipe is equipped with to the ceiling, and new trend supply-air outlet is located drain bar one end for new trend blows to the drain bar for the refrigeration adopts the furred ceiling structure of this embodiment, and the design parameter that is relevant in room is found according to relevant design specification to the assumption room designer number 3: the indoor design temperature in summer is 25 ℃ and the design relative humidity is 60%; the temperature of the dry bulb is 35 ℃ and the relative humidity is 80% calculated outdoors in summer. The fresh air quantity is preset to be 30m 3/(human x h) under the sanitary condition, the heat dissipation of personnel and other equipment is ignored, and the indoor initial temperature and humidity are the same as those of the outdoor.
The effective radiation refrigerating area is 30 square meters, the water inlet and outlet temperature is 13/15 ℃, the water speed is 0.5m/s, the inner and outer pipe diameters of the cold water pipes are 15/20mm,8 cold water pipes are parallelly and uniformly distributed on the ceiling side by side, each water pipe corresponds to 1 drainage plate and one drainage plate, and one side of each drainage plate with lower side is communicated with the inlet of the collecting device to collect dew.
Cold quantity calculating method
According to the related example, assuming that the cooling capacity q of unit area after the radiant cooling area is reduced (including convection heat transfer and radiant heat transfer) is q=50w/square meter, the cooling area is s=30square meter.
It can be seen that:
Refrigerating power
P＝q*s＝50W/m2*30m2＝1500W
Refrigerating capacity required by room refrigeration
Q＝m Flat plate ×c Flat plate ×Δt＝(1.060kJ/(kg·K)+1.028kJ/(kg·K))/2×(157.65kg+
167.31kg)/2×(35℃-25℃)＝1696.29kJ
Time required for refrigeration
t＝Q/P＝1696.29kJ/1500W＝1131s＝19min
Dew condensation calculation:
From the dry bulb temperature of 35℃and the relative humidity of 80%, the moisture content was d1= 28.92g/kg, the specific volume was v1= 0.9134m 3/kg, and the specific heat was c1=1.060 kJ/(kg.K).
From the dry bulb temperature of 25℃and the relative humidity of 60%, the moisture content was d2=11.90 g/kg, the specific volume was v2= 0.8607m 3/kg, and the specific heat was c2=1.028 kJ/(kg.K).
Initial room air parameters:
Wet air quality
M1＝V/ν1＝8m×6m×3m/0.9134m3/kg＝157.65kg
Wherein V is the volume of the room,
Dry air mass
m1＝M1×1000/(1000+d1)＝157.65kg×1000/(1000+28.92)＝153.22kg
Quality of water vapor
m2＝M1-m1＝157.65kg-153.22kg＝4.43kg
Air parameters in room after stable operation:
Wet air quality
M2＝V/ν2＝8m×6m×3m/0.8607m3/kg＝167.31kg
Dry air mass m3=m2×1000/(1000+d2) = 167.31kg×1000/(1000+11.9) = 165.34kg
Quality of water vapor
m4＝M2-m3＝167.31kg-165.34kg＝2.00kg
It can be seen that:
dew mass
m5＝m2-m4＝4.43kg-2.00kg＝2.43kg
Referring to the related case, the drain plate has 90% of dew condensation on the hydrophobic side, 10% of dew condensation on the hydrophilic side,
It can be seen that:
Moisture condensation amount on hydrophobic side
m6＝m5×0.9/19×60＝2.43kg×0.9/19×60＝6.561kg/h
Hydrophilic side condensation amount
m7＝m5×0.1/19×60＝2.43kg×0.1/19×60＝0.729kg/h
The suspended ceiling structure of this embodiment is set up and also can collect well to this kind of big dew, can not appear the phenomenon of dripping.
Calculating the water quantity:
From the above, the inner diameter d=15mm of the pipe and the temperature of the water inlet and outlet are 13/15 ℃, the water velocity v=0.5 m/s and the density ρ=1000 kg/m 3 of water.
It can be seen that:
cross-sectional area of cold water pipe
s′＝(d/2)2×3.14＝(0.015m/2)2×3.14＝0.000314m2
The radiation cold water quantity is
q′＝6×s′×v×ρ＝6×0.000314m2×0.5m/s×1000kg/m3＝0.53kg/s＝31.8L/min
Power consumption calculation
According to 31.8L/min of cold water flow, a BJZ-guangdong campsis stainless steel water pump can be selected to meet the requirement, and the power is 550w.
According to the condition that the fresh air quantity is 90m 3/h, 1550BHL ball axial flow fan is selected to meet the requirement, and the power is 38W.
The power is 588w in the refrigeration process, and after the indoor cooling reaches the requirement, the power can be properly regulated, so that the indoor temperature stability can be met. The energy-saving air conditioner is used for a traditional air conditioner in a room with a square meter of 48 ℃ and has a general power of about 2000w, and compared with the traditional air conditioner, the traditional air conditioner has the energy-saving effect of about 60%.
