Hot water system scheme of high-grade hotel

In view of the characteristics of hotels, hotels and small enterprises, such as diversified hot water modes, long hot water consumption time, and attention to the stability and energy saving of hot water equipment, the following low-carbon comfortable hot water solutions are recommended according to different regional characteristics:

I. Air source heat pump

The air source heat pump hot water system is mainly composed of air source heat pump unit, hot water storage tank, system automatic control box, circulating pipeline, circulating water pump and valve. It takes air source heat pump unit as the main heating mode, and electric heating built in the water tank as the auxiliary heating mode. The system gives priority to the use of air source heat pump to the maximum extent. When the heat pump unit cannot be started, the electric heating equipment is operated for auxiliary heating. Air source heat pump and electric heating tube can not only work independently in an effective period, but also make up for each other to ensure the hot water supply of the system.

Second, the combination mode of solar energy and heat pump

The solar air source heat pump system is mainly composed of a flat plate collector, an air source heat pump unit, a hot water storage tank, an automatic control box of the system, a circulating pipeline, a circulating water pump and a valve. The system mainly uses solar heating, supplemented by air source heating; According to the sunny days in spring, summer, autumn and winter, solar energy heating is given priority to as much as possible to reduce the energy consumption of auxiliary heat pump heating; After solar heating, when the temperature is insufficient, the heat pump unit will carry out auxiliary heating; In order to save energy, when the solar radiation intensity is enough, the solar energy system works in the temperature difference cycle mode, and the heat pump unit runs less or does not start; When the solar radiation intensity is not enough, the heat pump unit operates, so that not only the solar energy and the heat pump can work independently and efficiently within the effective period, but also can make up for each other to ensure the hot water supply of the system.

Third, the gas-fired boiler for solar energy

The commercial condensing gas water heater system of solar energy distributor is mainly composed of flat plate collector, commercial condensing gas water heater, hot water storage tank, automatic control box of the system, circulating pipeline, circulating water pump and valve. The system is mainly heated by solar energy, supplemented by gas water heater; According to the sunny days in spring, summer, autumn and winter, solar heating is given priority to as much as possible to reduce the energy consumption of auxiliary heating of gas water heaters. After solar heating, gas water heaters perform auxiliary heating when the temperature is insufficient; In order to save energy, when the solar radiation intensity is enough, the solar energy system works in the mode of temperature difference cycle, and the gas water heater runs less or does not start; When the solar radiation intensity is insufficient, the gas water heater operates. Solar and gas water heaters can not only work independently in an effective period, but also make up for each other to ensure the hot water supply of the system.
