I. Introduction

The school is a place to teach and educate people and cultivate the talents of society. In order to improve the living conditions of students, it is very urgent and very important for each student to use comfortable domestic hot water to solve their living water. The school hot water project should solve these problems: 1. The water use time is concentrated, and the water consumption is very short in a short time. 2. Students have higher requirements for hot water temperature, serious waste, and poor management. 3. Minimize installation costs, usage costs, and maintenance costs. 4. Take into account environmental protection, safety and other factors.

As a new energy-saving and environmentally friendly air source heat pump hot water machine can solve the hot water problem in schools and meet the requirements of the school hot water project.

Second, the solution

Take a school hot water project as an example.

1. Project Overview: The renovation project of a school's bathroom air source system requires a small part of the independent bathroom and public bath to provide hot water to meet the hot water needs of 3,000 students.

School requirements:

1 system outlet temperature is constant at 55 °C, water supply time can be set

2 equipment intelligent operation, no need to take care of the person, automatic alarm when the fault occurs

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
