| Method/Items | Air-cooling type | Glycol type | Water-cooling type |
|---|---|---|---|
| Medium | Air | Glycol solution | Coolant |
| Initial investment | About 110% | About 125% | 100% as the reference |
| Freezing efficiency (22C,50%) | About 85% | About 75% | 100% as the reference |
| Operation cost | About 110% | About 120% | 100% as the reference |
| Subsidiary facilities | Indoor condensers and subsidiary pipes | Cooling towers, circulation pumps and subsidiary pipes | Dry coolers, circulation pumps and subsidiary pipes |
| Advantages | ▷As condensation takes place using the outside air, subsidiary facilities are simple and it is convenient to manage operation. | ▷ Can be used for all seasons as the chilling is based on the glycol cooling method that uses sealed-type condensers. | ▷Chilling efficiency is high because the condensation takes place using coolant |
| ▷Initial investment cost is low | ▷Easy to control and simple to maintain regardless of seasons | ▷Almost not to be influenced by the change in the outside conditions | |
| ▷Easy to repair and costs less to maintain | ▷Less contamination of subsidiary facilities as the system is a sealed-type model ▷ A comprehensive system that is suitable for high-rise buildings as it is not limited in the length of piping ▷ Glycol is resistant to corrosion, which will help prevent scale inside pipes and enhance thermal conductivity and provide semi-permanent durability | ▷Less restriction in terms of the distance between the indoor unit and the outdoor unit | |
| Disadvantages | ▷As condensation takes place using air, any change in the outside air would cause somewhat burden onto the compressor. ▷Restriction in terms of the distance between the indoor unit and the outdoor unit | ▷The initial investment cost is slightly higher when compared with other systems ▷Freezing efficiency is low as the glycol solution is used | ▷As there is a risk of the coolant unit breaking due to severe cold weather in winter and the system is an open-type model, the system could fail when there are pollutants with the subsidiary facilities |
