Application of Commercial heat pump water heater in centralized hot water supply system
The scope of application of centralized hot water supply system: shopping malls, hotels, hotels, schools, hospitals, baths, factories, companies, government agencies, enterprises and institutions, and whole-house hot water projects for homes and villas.What you need to know when designing a centralized hot water supply system
1. Determine the amount of hot water and heating capacity required
2. Heating equipment selection (Commercial heat pumps, solar energy, boilers, heat pump water heaters, heat recovery capacity)
3. The selection of the system scheme and the design and calculation of the water distribution pipeline.
4. Selection of supporting facilities: hot water tank, circulating water pump, control system, etc.
The selection of central hot water equipment needs to combine various factors, such as water consumption per hour of hot water, heat consumption of hot water, heating capacity of the unit, temperature difference between cold and hot water, hot water utilization rate, hot water tank capacity, material, and hourly change of hot water Factors such as coefficients.
Apartment hot water engineering solution
1. Water is complicated
Solution: The design is based on 2 people in each room, and the shower is about 100L per person. If there is a bathtub, each bathtub is calculated according to the actual volume.
2. Use water at irregular points throughout the day
Solution: The apartment needs to be equipped with a heat preservation water tank according to the calculation results of the water volume. 60% of the hot water consumption throughout the day is stored in the heat preservation water tank. The heat preservation temperature drop of the water tank does not exceed 5°C (outdoor) and 3°C indoors.
3. Peak water consumption
Solution: The water tank volume is designed enough, and the heating capacity of the unit is added during the peak period, and the design temperature drop does not exceed 5℃.
4. Heating cost issue
Solution: Both the Commercial Heat Pumps Hot Water system and the solar water heating system are renewable energy sources, and the operating costs are relatively low.
5. Does not affect the appearance
Solution: Install the solar energy, air heat pump water heater group and the water tank to the designated location, and send the hot water to the place where it is needed through the hot water pipe network, without affecting the appearance.
Hot water project solution for dormitory living area
Design principles of hot water project in dormitory living area:
Refer to the unique actual hot water demand of the dormitory living area, plan a personalized plan, and the system design direction is energy-saving, safe and stable; to meet the user's hot water demand.
In addition, taking into account the maintenance, one backup and one use in the event of an accident, according to the water demand, configure the pipes and accessories; units in need can consider equipped with a remote control system.
Hot water system project recommendations for dormitory living area: solar energy system engineering and Low Temperature Heat Pump water heater system, or a combination of solar energy + air source. Energy saving, environmental protection, low operating costs, and strong system stability are the original design intentions.
Questions to be understood in the hot water project plan of the dormitory living area:
1. Total number of bathing people throughout the day
2. Concentrated bath time
3. Number of bathing persons per hour (number of nozzles)
4. Whether it is equipped with electric auxiliary power supply (electric auxiliary power consumption is higher)
Hot water engineering solutions for dormitories (gymnasiums, yoga studios, schools)
1. Regular water supply, fixed-point water supply
Solution: The dormitory hot water project can be managed by IC card, and the IC card can be pre-set. When taking a bath, the card is swiped to fetch water, and the amount of water is used as needed to avoid wasting hot water.
2. Can not stop the hot water supply
Solution: The hot water system of the hotel should be designed with circulating water for bathing water to ensure that hot water will come out soon after the guests turn on the tap. When the outdoor temperature is low, electric auxiliary heating can be used to ensure the normal use of hot water in the room.
3. Peak water consumption
Solution: The water tank volume is designed enough, and the heating capacity of the unit is added during the peak period, and the design temperature drop does not exceed 5℃.
4. Heating cost issue
Solution: Commercial heat pump water heater system and solar hot water system are both renewable energy sources, and the operating cost is relatively low.
5. Does not affect the appearance
Solution: Install the solar energy, commercial heat pump water heater unit and water tank to the designated location, and send the hot water to the place where it is needed through the hot water pipe network, without affecting the appearance.
