It is an important part of construction enterprise management to care about the living environment of front-line construction personnel and maintain the vigorous combat effectiveness of the construction team. The perfect heating, cooling and domestic hot water system of the temporary construction project is the key element of the work and life quality of the construction personnel.

The temporary buildings on the construction site of the project are mainly in the form of containers, color steel prefabricated houses, etc. The construction standards are gradually standardized, and the environmental protection requirements are increasingly strict. Based on STS high-end heat pump technology with independent intellectual property rights, Kcalin New Energy Co., Ltd. has developed Kcalin modular air conditioning integrated system for temporary construction projects with intelligent and integrated water transmission module.

The system is composed of STS Kcalin low-temperature air source heat pump unit, hydraulic transmission module and multi-style terminal equipment to meet different needs. What are the advantages of this system?

1. Cold and hot efficient

Cooling in summer and heating in winter have reached the first level of energy efficiency standards.

2. No frost disturbance and small attenuation in winter heating

STS heat pump adopts flexible defrosting technology and intelligent defrosting. During the defrosting process, the compressor does not need to be stopped and unloaded to realize uninterrupted heating in winter and small heat attenuation.

3. Modular design

Various combinations are suitable for projects of various scales.

4. Wide application range

STS heat pump unit adopts low-temperature heat pump technology, and is widely used in severe cold zone C, severe cold, hot summer and cold winter, hot summer and warm winter and mild areas.

5. Convenient operation and maintenance

Adopt microcomputer automatic control, start and stop with one button.

6. Easy installation and disassembly

The modular design of the unit is more convenient to install and disassemble than the traditional split air conditioner and multi-split air conditioner.

7. Reuse

The service life of the unit is more than 15 years, and the temporary construction project can be reused.

8. Energy conservation and environmental protection

The unit is cold in summer and warm in winter, which can replace split air conditioners, electric boilers, electric heaters and other equipment.

9. Safe and reliable

The integration of power supply system and control system greatly reduces the potential electrical safety hazard.

The prefabricated temporary construction project of CCCC Third Highway Engineering Bureau Co., Ltd. (hereinafter referred to as "CCCC Third Highway Engineering Bureau") is located in Mentougou District, Beijing, with a construction area of about 2000 square meters. The system adopts Kcalin modular air conditioning integrated system to provide the working and living requirements of cooling in summer, heating in winter and domestic hot water throughout the year for the project construction site personnel. The system adopts two Kcalin KLDCS65DW1B2 air source heat pumps, one Kcalin KLDRS20DW1B2 heat pump water heater unit, one Kcalin KLHM80 hydraulic transmission module unit, and 49 wall-mounted fan coil units. After using the system, the living and office environment of the construction site staff has been greatly improved. Beautiful, comfortable, healthy, energy-saving and environmental protection, which shows the overall image and management level of the construction enterprise.
