Hotels 24 Hours Hot Water Supply Air Source Heat Pump High Temeprature 55C
Introduction
The hotels have 250 rooms in total. In four seasons need 55C daily use hot water in 24 hours.
The hot water request volume is around 40 tons per day.
According to the features of hotel hot water usage, the peek time is 16:00 to 1:00, about 9 hours. The heating time should be within 15 hours.
Local winter temperature is -5C ~-8C .
Design summary
| No | Conditions | design request |
| 1 | Hot water volume | 40 tons per day |
| 2 | 2 storage water tanks | 10 ton each |
| 3 | 2 heating water tannks | 5 tons each |
| 4 | Air source heat pumps 25Hp | 4 sets |
| 5 | heating time | 13 hours |
System
Every heating tanks match with two air source heat pumps, when water in heating water tanks reach 55C, the air source heat pump stop working, hot water move to insulated storage water tanks.
Storage water tanks has water level gauge, when hot water reach the highest level, water supply will stop.
Air source heat pumpFeatures
1) High efficiency and energy saving:
high heat collecting efficiency and low operating cost: the ratio
of output energy to input energy is COP up to 4 or more. The
energy efficiency ratio of ordinary electric water heaters is not
more than 0.95, and the energy efficiency ratio of gas and
oil-fired boilers is generally only 0.6-0.8. The energy-efficiency
ratio of coal-fired boilers is lower, generally only 0.3-0.7.
Therefore, its operating cost is 67% lower than that of gas water
heaters, 75% less than electric water heaters, 60% less than
oil-fired boilers, and more than 30% more energy-efficient heating
solar energy.
2) Green and environmental protection:
the special refrigerant for heat pump is used, and no waste water
is discharged. The entire system is also free of waste residue,
waste heat, and is absolutely environmentally friendly.
3) Safe and economical:
no worries, the heating method realizes complete water and
electricity separation, and fundamentally eliminates the safety
hazards such as flammable, explosive, electric shock, dry burning
and carbon monoxide poisoning.
4) Modular intelligent control function:
It can flexibly add multiple units to form a hot water supply system according to the actual needs of users, realize modular control, automatically control and adjust the running time of each unit and the order of operation, and ensure the total of each unit. The running time is consistent, achieving efficient and optimized operation of the entire hot water supply system.
