What is the working principle of hotel hot water system?

Almost everyone of us has stayed in a hotel, so we all know that the hot water system of the hotel is very important. Back to the hotel at night, we will take a shower and wash clothes. At this time, a convenient hot water system is needed to supply hot water all day. It is always available, welcomed by check-in passengers and brings great convenience to people. Let me introduce the hot water system of the hotel to you.

Heating equipment

Heating equipment is an energy conversion equipment, which outputs steam, high temperature water or organic heat carrier with certain heat energy to the outside. 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.

heat exchanger

Because of the high water temperature and large water supply, the heating equipment without coating 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.

Thermal storage equipment

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

circulatory system

The hot water pipe network controls the operation of the circulating pump according to the backwater temperature 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.

Direct heating mode

The direct heating mode of budget 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 end of the hotel without the need to configure a heat exchanger, an insulated water tank and a secondary side circulating pump.

Indirect heating mode

Take a hot water boiler or a vacuum boiler as an example. Because of the high water temperature and large make-up water, the uncoated boiler liner will be easily corroded, so 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.

? So how is the hotel's hot water system made up? In fact, the hotel hot water system is that one or more heating devices deliver hot water to the shower and washbasin in each room through the hot water pipe network, and at the same time ensure the hot water consumption point by using the circulating pump. Usually, as soon as the hot water system of a hotel is hot, guests can enjoy 24 hours of sufficient hot water. The above is the hotel hot water system I introduced to you. I hope I can help you.
