I. Introduction
 
In the production and life of enterprise factories, hot water is a necessity. Usually, enterprises will establish equipment houses to store heating equipment. Gas boilers, oil-fired boilers, etc. are commonly used. These environmental wastes require further generation of waste gas and waste water. Waste slag equipment will be eliminated. As a new energy-saving and environmentally-friendly high-tech product, the air source heat pump water heater can replace these heating equipments well and provide hot water solutions for enterprise factories.
 
Second, the solution
Take the hot water project of a staff dormitory in an enterprise as an example.
1. Project Overview: In order to improve the living standards of employees, the company established an air source heat pump hot water system to provide domestic hot water for 1,500 employees.
 
Enterprise requirements:
1 can meet the bathing needs of 1,500 employees.
2 The centralized operation time of the unit is placed in the valley power stage, saving operating costs.
3 equipment is stable, safe and reliable, providing hot water 24 hours.
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)
Heat pump product samples and instructions (Guangzhou Yaohua Refrigeration Equipment Co., Ltd.)
Operation data of heat pump intelligent environment simulation laboratory (Guangzhou Yaohua Refrigeration Equipment Co., Ltd.)
Information provided by Party A 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.
 
Third, the conclusion
The air source heat pump hot water system of the enterprise factory has high efficiency and energy saving, intelligent regulation, which can control the running time of the unit in the valley time period, which is convenient for the management of the enterprise, not only meets the domestic hot water demand of the employees, but also saves the operating cost of the equipment.
