Air can be commercial hot water selection ----- hotel

The hotel's hot water system is an important system of hotel facilities, a good hotel hot water system can not only ensure that guests enjoy comfortable hot water 24 hours, enhance the image of the hotel, and a reasonable design of the hotel hot water system scheme, but also according to the actual needs of the hotel to configure its economic and energy-saving operating costs, extend the service life of the system. At present, there are five common hotel hot water solutions:

1, air energy + solar energy features: safety, environmental protection and clean, comprehensive energy-saving effect is very good, the initial installation cost is high, and the later failure maintenance point is more

2, air energy hot water features: water and electricity separation, safe and reliable, long-term stable operation of the unit, 75% energy saving than ordinary hot water, short cost recovery cycle. The operating cost is only 1/4 of that of electric water heaters and 1/3 of that of kerosene and gas water heaters. It is easy to install, does not require special management, fully automatic operation, and has a life span of more than 15 years.

3, solar hot water features: need to have a large sunny installation site, auxiliary heating is not energy-saving, there are security risks, winter ambient temperature is low season failure points.

4, gas and oil boiler characteristics: not energy saving, not environmental protection, not safe enough, need special care, late operation and maintenance costs are high, most hotels are no longer used, individual electricity unstable areas will be used in the hotel emergency backup plan.

5, the characteristics of the electric boiler: no energy saving, water and electricity are not completely separated, there are greater security risks.

Today we will focus on the selection of air energy. The hotel is mainly selected according to the star of the hotel and the number of rooms.

Generally ordinary small hotels, each room per day according to 100L design water consumption can meet the normal use needs.

For large hotels with relatively large scale, the design water consumption per room of 200L per day can meet the normal use needs.

Those with bathtubs need to be matched to 500L per room per day. Water consumption regardless of north and south, is a universal design.

The selection of the host is mainly based on the coldest ambient temperature in winter. So let me give you an estimate.

In areas above 10℃, the ratio between the main engine and the water tank is 1P: 1T.

In areas above -7℃, the ratio between the main engine and the water tank is according to 1.5P: 1T ratio.

In areas above -20 ° C, the ratio between the host and the water tank is matched according to 2P: 1T.

According to this configuration, water demand can be met in the coldest part of winter. And the hotel is a 24-hour water use. Generally, the water tank can be appropriately reduced, and the main engine can be as large as possible. So we don't run out of hot water in winter.

Some friends who do hotels, in order to save costs, will also take into account the reduction of the host, and then add distribution auxiliary heat. This plan is also no problem, as for whether it is cost-effective, you have to calculate the operating cost of the hotel's hot water consumption. Do hotel friends can refer to themselves. Try to avoid stepping in potholes. I am Liu Yong of Sixton, a professional manufacturer of heat pump, and I will popularize some knowledge for you from time to time.
