One thousand square metres of large industrial workshops, like a giant “climate regulator”, address the challenges of summer heat and harsh winter. Unlike common offices, the layers are generally above 6 metres high, with large space, high equipment heat dispersion and often less powerful traditional air-conditioning systems。
I. Mainstream integrated solutions (refrigeration + heat production)
1. Multi-line central air conditioning system (vrv/vrf)
Application scenario: complex layout, closed workshop with temperature control
Core strengths:
A set of outdoor mainframes connected to multiple interior end-of-doors, allowing both cooling and making hot
Variable frequency technologies are energy-efficient and partially energy-efficient, avoiding energy waste
Operational stability, maintenance of simplicity and support for independent control of temperature in different areas
Cannot initialise evolution's mail component
Refrigeration is estimated at 150-200w/m2 and total demand is approximately 150-200kw
Selecting to use the energy efficiency ratio (iplv>6. 0) group
Indoor machines use windpipes or current aircraft units according to the distribution of work places to ensure a smooth flow of wind over long distances
2. Wind cold module modular air conditioning (heat pumps)
Applicable scenario: open workshop, water-scarce area
Core strengths:
Modular design, flexible extension, phased input
Heat pump technology meets both refrigeration and heat production needs, with heating energy efficiency up to 2. 5-4. 0
No cooling towers, easy installation, easy maintenance
Cannot initialise evolution's mail component
Use of high-pressure wind pipes as an interior end to ensure uniform wind delivery in 1,000 m2 space
Configure smart control systems to monitor temperature and humidity automatically in real time
3. Evaporation cold-saving electric air conditioners (garden jets)
Application scenario: high-temperature dry areas, 24-hour workshops
Core strengths:
30-40% reduction in energy consumption: pre-refrigerant reduction of compressor load through "evaporation cooling + mechanical cooling" complex
Environmentally friendly refrigerants, consistent with green trends
Multi-connected design, smart connection, even coverage
Configure reference:
1,000 m2 workshop could be installed using a 4-6-bed jet mix
Equipment may be placed on the roof or on the outside, with no indoor space provided through the windpipe
Temperature can be stabilized at 24-28°c with 50-65% humidity
Economic/specified scenario
4. "environmental air conditioning plus industrial fan" combination (refrigeration + ventilation only)
Applicable scenario: open workshop, personnel intensive, limited budget
Programme composition:
Environmentally friendly air conditioners: using water evaporation to cool, low initial investment, running costs of only 1/8 of traditional air conditioners
Large industrial fans: a 7. 3-metre diameter fan covering an area of 1445 m2 to drive the flow cycle and enhance human comfort
5. High-space heater units (jet-jet ceiling)
Applicable scenario: higher-level industrial plants (over 8 metres)
Technical characteristics:
Use type c heat exchangers and aluminum wings for heat efficiency improvement
Support thermal recovery function, i. E. Refrigeration and waste heat recovery for production hot
Flow-mitigation distance of 30-50 metres, suitable for a wide range workshop
Iii. Key selection parameters and calculations for air conditioning options
1. Cold thermal load estimates
Refrigeration: 150-200w/m2 x 1000m2 = 150-200kw (up to the limit in case of personnel density or equipment heating)
Heat preparation: 80-120kw estimated at 80-120w/m2 (heat load correction for cold areas)
2. Equipment selection checklist
