I. Introduction

 

The hotel hot water system usually adopts a centralized hot water supply system, that is, one or more heating equipments deliver hot water to the showers and wash basins of each room through the hot water pipe network, and use the circulation pump to ensure hot water points. Ready to use, allowing passengers to enjoy 24 hours of hot water. Therefore, there are such requirements for heating equipment: small floor space, high thermal efficiency; safe and reliable operation, high degree of self-control; centralized or decentralized equipment according to room layout.

 

The air source heat pump water heater can meet all the requirements of the hotel for heating equipment, providing passengers with safe and comfortable hot water for 24 hours.

 

Second, the solution

Take the air source heat pump hot water project in a certain area as an example.

1. Project Overview: The hotel provides 24-hour hot water for VIP suites and 50 tons of hot water per day.

 

Hotel requirements:

124 hours of hot water, efficient water

2 The water temperature can be self-regulated, intelligent operation, no need to take care of

3 equipment operation is safe and reliable, high stability and long service life

4 unit failure can be repaired in time, regular maintenance and maintenance

 

2. Meteorological parameters

 

3. Design basis

Building Water Supply and Drainage Design Manual

Design code for building water supply and drainage (GB50015-2003)

Design code for building water supply and drainage and hot water supply

Water supply and drainage national building standard design atlas

Heat pump water heater for commercial or industrial use and similar purposes (GB/T 21362-2008)

Heat pump hot water system selection and installation (06SS127)

Operation data of heat pump intelligent environment simulation laboratory (Guangzhou Yaohua Refrigeration Equipment Co., Ltd.)

Information provided by the hotel and on-site survey

 

Note: Although the relevant data in the above tables cannot fully reflect all the operational data, it can reflect the main operating costs of the system from a relatively macroscopic aspect. B, D, E are boiler-type schemes, which need to increase the daily maintenance, inspection and management personnel costs of the boiler. Among them, the natural gas pipeline laying needs to increase the account opening fee; C is the steam heat exchange scheme, which also needs to increase the account opening cost, equipment daily Maintenance, inspection and management personnel costs. A is a heat pump hot water solution, which can realize unmanned management throughout the year, the system runs automatically, there is no high-risk equipment such as pressure vessels, and the safety performance is stronger than the boiler.

 

Fourth, the conclusion

The hotel's air source heat pump hot water system has 24-hour constant temperature water, high intelligence, safety and stability, to meet the passenger's hot water demand, is the hotel's energy-saving choice.
