Gas vacuum hot water boilers are commonly used in people's lives and can be used for heating and domestic water in hotels, schools, troops, and businesses. The vacuum boiler uses a built-in heat exchanger, which occupies a small area, has a simple HVAC system design, and is easy to install. It is very popular among users and has an increasing market share. What is the model of a gas vacuum hot water boiler? How to select a hotel vacuum hot water boiler?
1. Gas vacuum hot water boiler model
Take 2.8 MW as an example, the gas vacuum hot water boiler model is Z-WNS2.8-80/60-Q
Z means vacuum
WNS2.8 means horizontal internal combustion chamber furnace, rated thermal power is 2.8MW
80/60 means outlet water temperature is 80 degrees, return water temperature is 60 degrees
Q means the fuel is gas fuel
2. How to select a hotel vacuum hot water boiler
1. Heating selection: 50W×heating area
2. Calculation of hot water consumption: (estimated based on the number of bathers)
Q=qh·n
Q: Maximum daily hot water consumption t/h
q: Per capita hot water consumption quota, take qh=120L
n: Number of bathers per day n＝80×2=160
Q=120×160=19200（L/h）=19.2t/h
2. Heat for bathing
Take the hotel bathing coefficient 1/7, and divide the bathing water consumption by the fixed coefficient 19200/7=2743
The water supply temperature is about 15 degrees, and it is heated to 60 degrees for bathing water;
Total heat required: 2743×(60-15)≈120,000 kcal
3. Water tank selection:
Take the hotel shower coefficient 1/5, and select the water tank type 19200/5≈4m³; the water tank utilization rate is 0.7
The final water tank selection is 4/0.7≈6m³.
The gas vacuum hot water boiler has few auxiliary machines, simple installation and convenient operation.
