What is the composition of the hotel hot water system?

Speaking of hotels, what impressed us the most was the hotel's hot water system. The hot water system of the hotel is open 24 hours a day. Whenever you return to the hotel, you can enjoy the comfortable life brought by hot water. But do you really know the hotel hot water system? What is the composition and heating mode of hotel hot water system? The following small series will further introduce the composition and heating mode of the hotel hot water system for you.

1. heating equipment: heating equipment is an energy conversion equipment, which outputs steam, high-temperature water or organic heat carrier with certain heat energy. At present, the heating equipment widely used in budget hotels mainly includes: positive displacement water heater, hot water boiler, heat pump hot water unit, solar energy, vacuum boiler and steam boiler.

2. Heat exchange equipment: Due to the high water temperature and large water supply, the uncoated heating equipment will be easily corroded, usually to prolong the service life of the heating equipment and ensure the water quality. Use plate heat exchanger or volumetric heat exchanger to exchange heat between heating equipment and hot water point.

3. Thermal storage equipment: In order to ensure sufficient hot water, some heat source equipment is DC products, and economy hotels need to be equipped with open water tanks or closed water tanks for thermal storage. The volume of water tanks can be determined according to actual consumption.

4. Circulation system: The hot water pipe network controls the operation of the circulating pump according to the backwater temperature, so as to ensure that passengers can generate hot water immediately when they open the shower or washbasin. At present, budget hotels require 10 second hot water.

1. Direct heating mode: The direct heating mode of economical hotels usually relies on a hot water boiler with a certain volume of liner, which directly heats the water in the liner with gas or electricity, and can directly transport the hot water to the hotel terminal without the need to configure a heat exchanger, an insulated water tank and a secondary side circulating pump.

2. Indirect heating mode: Take the hot water boiler or vacuum boiler as an example, because the uncoated boiler liner will be easily corroded due to high water temperature and large supplementary water, it is necessary to indirectly heat the boiler water through heat exchange equipment; Take a heat pump hot water unit or solar energy system as an example. The heat pump hot water unit or solar energy is limited by the output power of the unit and the stability of the heat source. The system must be equipped with large-tonnage heat storage equipment to store heat to meet the peak hot water demand.
