What central air conditioning does a five-star hotel use?

When designing the air conditioning scheme of a five-star hotel, it is necessary to comprehensively consider its building scale, operation characteristics and climate adjustment of the city, and reasonably design the system scheme.

Scheme A: Ultra-efficient centrifuge+heat recovery screw unit

Ultra-efficient centrifuges have high energy efficiency, and consume a small amount of electric energy to obtain a large amount of cold energy to provide refrigeration for all air-conditioned areas. At the same time, the heat recovery screw chiller can provide a lot of free domestic hot water for the hotel while cooling, reducing energy consumption. The high-performance fan-coil unit adopts the famous large impeller fan and low-noise motor, and with the exquisite box structure design, the operation noise of the unit is minimized and the air supply effect is the most comfortable.

Scheme B: Combination of frequency conversion and constant frequency centrifuges

Scheme B adopts the combination form of frequency conversion centrifugal unit and constant frequency centrifugal unit as the main engine, and makes full use of the high efficiency of frequency conversion centrifugal unit under partial load, so that the whole air conditioning system can take into account the full load and partial load operation conditions all year round, and the whole air conditioning system is always in the most energy-saving operation state. In addition, the combined air-conditioning box can use the advanced new wind heat recovery technology to provide a lot of fresh air for hotels, improve indoor air quality (IAQ), and greatly reduce the energy consumption for handling fresh air.

Scheme C: Water-ground source heat pump unit

Scheme C is the best choice for resort-style star hotels. The suburb is rich in water resources, so the rational use of water-ground source heat pump units can give full play to its advantages of high efficiency and versatility, and can meet the needs of air conditioning, heating and domestic hot water in hotels all year round. In addition, the refrigeration capacity of the water-ground source heat pump unit can be flexibly adjusted, which perfectly adapts to the changeable air conditioning load of the hotel and avoids the situation that the traditional air conditioning system is sometimes cold and sometimes hot. At the same time, a variety of high-performance terminal products can create fresh and comfortable indoor air quality (IAQ) enjoyment for hotels and provide the best rest environment for passengers.

Scheme d: heat recovery type air-cooled screw heat pump unit

Scheme D adopts heat recovery type air-cooled screw heat pump unit. In summer, the heat recovery air-cooled screw heat pump unit is used for refrigeration, and the condensed heat is recovered to make sanitary hot water for rooms and other places that need hot water. In winter, hotel heating uses heat pump units to make heating hot water, and at the same time uses heat recovery units to provide sufficient sanitary hot water for guest rooms. The same system meets the needs of hotel air conditioning, heating and domestic hot water, omits the traditional cooling tower and boiler, saves energy and reduces the initial investment of the project.
