Which way is better for hotel heating?

Abstract: With the rapid development of hotel industry, heating system is an indispensable and important facility for modern hotels, especially in the northern region. What are the heating methods in the hotel? General hotel heating methods include central heating, air conditioning, clean energy, steam boilers and heat exchangers, atmospheric hot water boilers and heat exchangers, vacuum hot water boilers, etc. So which is better? Let's look at the introduction first. Which way is better for hotel heating?

Hotels and other places need heating and sanitary hot water supply. Boiler is needed for heating and sanitary hot water supply. Hotels generally have the following heating methods:

1, using steam boiler to heat the heat exchanger.

This heating method generally uses the high-temperature steam generated by steam boiler to enter the volumetric heat exchanger for heat exchange, heating the hot water in the heat exchanger to supply sanitary hot water, while the steam generated by steam boiler is used to heat the hot water in the plate heat exchanger for heating.

The disadvantage of this heating method is that it needs secondary heat exchange, and the volumetric heat exchanger and plate heat exchanger will produce heat loss and the heat exchange efficiency is low. Moreover, the steam boiler is operated under pressure, which is in danger of explosion and unsafe. It must be operated by full-time firefighters, and it is rarely used now.

2, using atmospheric hot water boiler and heat exchanger.

Atmospheric hot water boiler with heat exchanger is a common heating method in hotels. Generally, the atmospheric hot water boiler is used to generate high-temperature hot water first, and then the generated high-temperature hot water is added with the hot water from the volumetric heat exchanger to supply sanitary hot water. The high-temperature hot water in the atmospheric hot water boiler is used to heat the plate heat exchanger to generate the hot water needed for heating.

Like the first heating method, this heating method requires secondary heat exchange. As long as there is secondary heat exchange, heat loss will occur. Atmospheric hot water boiler is relatively safe and generally does not cause explosion danger. However, the atmospheric hot water boiler is inefficient and easy to scale, which will lead to the decrease of thermal efficiency and even system risk after long-term use.

3. Vacuum hot water boiler is used to heat sanitary hot water.

Vacuum hot water boiler is a new trend in the field of hotel heating. Vacuum hot water boiler is a built-in heat exchanger, which can directly generate hot water with the required temperature. Therefore, the vacuum boiler is used for heating and sanitary hot water without secondary heat exchange. If it is used for sanitary hot water, only one hot water tank needs to be installed, while for heating, the outlet water can be directly used for heating by directly setting the outlet water temperature.

The advantages of vacuum hot water boiler used in hotel heating and sanitary hot water supply are as follows: ① Safety: the vacuum boiler runs under negative pressure, and there is no explosion danger, which is very safe. It is an inspection-free boiler specified by the state. ② The system is simple: water can be directly discharged, and multiple heat exchangers can be built in to supply heating and sanitary hot water at the same time. ③ High efficiency: high thermal efficiency, generally more than 94%.

4, air conditioning heating

Many hotels use central air conditioning for heating, which can be used all year round. But central air conditioning also has its disadvantages, such as high energy consumption and poor heating comfort. Generally, budget hotels in the south generally choose air conditioning for heating, while some hotels with small scale and few rooms can also use wall-mounted air conditioning for heating.

5. Central heating system

Hotels in the north generally choose municipal heating and boiler heating, because municipal heating is a safe and low-cost heating form. When the hotel property has conditions, municipal heating is the form of hotel heating.

6. Clean energy

At present, many hotels use clean energy for heating, such as air energy heat pump and ground source heat pump, which can be warm in winter and cool in summer, and can also provide hotel hot water, but the initial investment will be relatively large and the equipment installation and design will be professional.
