Description
Technical field
The present invention relates to air conditioning system, be specifically related to a kind of air-cooled heat pipe cold water air-conditioning system.
Background technology
Industrial premises, especially electronics industry toilet factory, due to its preferable enclosed structure sealing and thermal insulation
Can, even if in the winter time, it is required for giving refrigeration cool-down and could meet the humiture requirement of production environment.But, in China of China
North and the Northeast, owing to outside air temperature in winter is relatively low, some small-sized electronics industries and equipment manufacture workshop, winter
Season refrigeration system operating has more difficulty, such as: cooling by wind cannot start because outside air temperature is low；Water cooled chiller by
The intermittence (some small business or 8 hours dutys of laboratory, work by day, and have a rest in the evening) run in system causes
Outdoor cooling tube Louis be frozen split, freezing, etc..
In order to avoid these difficulties, the basic air-conditioning box AHU (Air Handle Unit) using return air to add new wind form, i.e. profit
After the outdoor new wind of low temperature and the mixing of workshop return air, carry out warming and humidifying process, lower the temperature in being then sent through workshop.This air-conditioning
System model is owing to using air cooling system, so that airduct is arranged in bigger space.If separated as many in Factory Building
Little area workshop, and there are humiture and purity requirements in each workshop, it is clear that and such air conditioning system layout is more difficult.
If being independently arranged a set of AHU in each little workshop, then can cause needing substantial amounts of equipment machine room to place AHU.And such as
1 set AHU is share in the most several little workshops, then airduct layout needs higher building floor height, and controls the warm and humid of each workshop
Need when spending to maintain its cleanliness factor the most difficult.Therefore, use AHU to need substantial amounts of equipment investment, make in the winter time
Time cold, cost performance is the lowest.
Therefore, when freezing in the winter time, the air conditioning system of prior art has the disadvantages that
1, refrigeration duty in winter is little and during discontinuous, water cooled chiller is not suitable for, the cooling tower supporting because of it and pipeline
Can be frozen bursting by freezing when system is not run；Cooling by wind cannot start when outside air temperature is too low.
2, use AHU, utilize the outdoor new wind of low temperature to indoor offer cold, cause equipment and airduct dimensional space demand big,
And control when humiture and cleanliness factor more difficult, and substantial amounts of equipment investment makes AHU cost performance low simultaneously.
