Product introduction

Talk about Engineering Experience of Factories, Schools and Troops

Whether it is a school, army or factory dormitory, the biggest characteristic is the large number of users and the large amount of water required, which means that the demand for hot water system is higher and the attention to the cost of use is higher.

Therefore, for dormitories, we will determine the actual water consumption as accurately as possible to reduce the initial investment cost; at the same time, we will design the internal pipeline system in detail to reduce unnecessary waste; for equipment working time control methods must also be based on the specific circumstances of each project. Corresponding adjustments will save Party A more expenses.

Dormitory engineering can be said to be the most familiar type of engineering.

Characteristics of Hot Water Engineering in Factories, Schools and Troops

Engineering characteristics


The water supply time is regular water supply. The water supply places are divided into centralized fixed-point water supply or indefinite-point water supply for each dormitory according to Party A's requirements.

It can be controlled by IC magnetic card port. By storing value in IC card in advance, users can draw water by swiping the card according to their own needs, which ensures the use of hot water according to their needs and eliminates the waste of personal water resulting in uneven water consumption.

Waste of water is serious

Special water control ports, such as water tickets and IC cards, are needed to avoid water shortage.

Water use is relatively stable

Design timing function, timing water supply

Usually there is peak and valley power supply

Equipment works regularly, using peak and valley power whenever possible

Higher security requirements

Install as far as possible in places not accessible to personnel or separated by fences. All units are equipped with leakage protection system.

Product advantage

Advantages of product accessories

Remote Monitoring System

On-line parameters of heat pump unit and its water system remotely

Special Compressor for Heat Pump

The special compressor for heat pump can meet the demand of heat pump under extreme application conditions.

Intelligent Electronic Expansion Valve

Accurately adjusting refrigerant flow rate, improving energy efficiency ratio and keeping system temperature running

Spiral heat exchanger

Improve the overall heat transfer efficiency, unique technology to ensure smooth waterway, uniform flow rate

Green environmental protection

Air source heat pump absorbs heat energy from the surrounding natural air, and has little impact on the environment. It is a real environmental protection equipment.

Energy saving and high efficiency

The energy efficiency of air source heat pump water heater heating equal amount of hot water can reach 4 times of that of electric heating, which saves a lot of electric energy.

Safety and comfort

Compared with other devices, it has better security performance. Air source heat pump water heater can ensure that hot water supply is sufficient 24 hours, namely, on-demand, stable temperature, comfortable and fast.。

Easy installation

Units can be installed outdoors, such as in the roof, the ground and other open-air places, occupying a small area, simple installation, no need to set up another working room to save space for users.

Application scenario
Selection reference

Basic parameters for design requirements of energy and hot water projects in factories, schools and troops

1. Local climatic conditions, annual minimum temperature

2. The grade and orientation of the hotel, whether the room has a bathtub and how big the bathtub is.

3. Number of rooms, water consumption in restaurants and kitchens

4. Water Supply Floor and Equipment Installation Floor

5. Equipment Installation Site (Load-bearing, Area)

6. Power Supply and Water Source
