Chiller Fan Coil System
Comprehensive school buildings include teaching buildings, libraries, office buildings, meeting rooms, laboratories, multimedia rooms, computer network centers, teacher and student activity centers, gymnasiums, etc. They have the following characteristics in terms of ventilation and air conditioning requirements:
※The air conditioning load demand is large and the energy consumption is high, with high requirements for energy conservation.
※With a high density of people, there are higher requirements for the quality of the circulating air.
※It occupies a large area, has a low utilization rate, and experiences significant load variations during use. Therefore, air conditioners are required to have strong adaptability and regulation capabilities.
※The usage time and requirements for each functional area vary, as do the temperature, humidity, cleanliness and load conditions needed. Therefore, there is a high demand for independent control and regulation of the rooms.
※Both teachers and students hope to study in a quiet environment and have strict requirements for the quietness of the air conditioning system.
※When building a new school, it is necessary to consider meeting the comfort and epidemic prevention requirements of the school staff from the very beginning of the construction.
We can offer
1.Solution for the air conditioning system for epidemic prevention in newly-built schools
2. Maintenance solutions for the current school epidemic prevention air conditioning system
2. Renovation solutions for the existing school epidemic prevention air conditioning system
★Applicable places
The functional buildings such as teaching buildings, comprehensive buildings and office buildings of large-scale comprehensive schools.
★Function
It can achieve indoor cooling, heating and fresh air supply
★The main products include
1) The cold and heat sources adopt the Grede high-efficiency falling film screw water (ground) source heat pump unit.
2) For air conditioning terminals, based on the building structure and functional requirements, options such as fan coil units, air purification treatment units, and medium-efficiency filters or disinfection devices at return air outlets can be selected.
★Characteristics of the ground source heat pump system with buried pipes
1) Renewable energy systems, energy conservation;
2) The system operates smoothly and has no impact on the environment, making it environmentally friendly.
3) Low annual operating costs and long service life.
★System and product features
1)By implementing four core technologies - flow control, efficient falling film evaporation, efficient oil separation and return technology, and Internet of Things remote intelligent services, the COP is 6.58 and the ACOP is 5.42. Compared with the full-liquid type unit, the operating cost is saved by 30%, and the energy efficiency of the unit can be increased by up to 10%.
2) The national patented falling film evaporation technology has a heat exchange efficiency that is over 15% higher than that of traditional flooded evaporators, reduces the refrigerant charge by 20%, enhances the oil return effect, and can effectively reduce the unit volume by over 20%, providing more space for the layout of the machine room.
3) Equipped with a self-developed NB-IOT remote intelligent control module for the Internet of Things, it can be operated via a mobile phone APP, eliminating the need for dedicated personnel to stand by.
