Travel Trailer Ac installation for oversized trailer-mounted motorhomes has entered a completely new professional field. Its core principle has evolved from “installing a single device” to “integrating a heavy-duty, high-power subsystem.” Ordinary motorhome installation experience is far from sufficient; it must be completed by a top-tier professional team.
Core Concept: This is not installation, it’s systems engineering integration.
For oversized trailers exceeding 10 meters or even longer, a single air conditioner typically cannot meet the cooling needs of the entire vehicle. Therefore, the solution usually involves installing two or more roof-mounted air conditioners, which brings about a qualitative change:
1. Structural Load-Bearing Capacity: Multiple air conditioners (each weighing approximately 50-70 kg) combined with dynamic driving loads place a huge strain on the roof.
2. Electrical Heart: The total power of multiple units can exceed 3000W, posing an extreme challenge to the battery, inverter, and charging system.
3. System Coordination: How to strategically plan, control, and distribute cooling capacity to avoid mutual interference. For Travel Trailer Ac design and installation, visit www.busclima.com or contact busclima@kingclima.com for more technical support.
Travel Trailer Ac – Professional Planning and Design
1. Conduct professional heat load calculations based on the trailer’s dimensions, insulation material, window area, and the climate of the usual location.
2. Install 2-3 medium-to-high power (15,000 BTU) DC inverter air conditioners. Advantages include redundancy (cooling is still available even if one fails), zoned control, and relatively standardized installation.
3. Professional assessment is essential: the original roof structure typically cannot withstand the dynamic load of multiple air conditioners (the impact of braking and bumps is 2-3 times that of a stationary structure).
4. A through-type reinforcing longitudinal and transverse beam is required inside the roof to form a robust “cage” frame. The material is high-strength aluminum profiles or steel, welded/riveted to the main frame of the trailer. This is an absolute prerequisite for installing on oversized trailers!
5. Calculate total power consumption. For example, two 1500W air conditioners operating simultaneously require 250A of current on a 12V system. This means you will need a 12V lithium battery pack of at least 800-1000Ah (or a corresponding 48V system).
6. If using AC air conditioning, the inverter power must be sufficient (e.g., dual 3000W inverters in parallel). The charger power must also be matched to ensure rapid recharging.
7. The main power supply cable must use heavy-duty multi-strand copper cable (e.g., 50-70mm² cable for each air conditioner).
8. Industrial-grade DC circuit breakers, electromagnetic contactors, and surge protectors must be installed.
9. The circuit design must support branch control, short-circuit protection, and voltage monitoring.
Travel Trailer Ac – Professional Installation
1. Accurately mark the positions on the reinforced frame and drill holes using professional tools. The edges of the holes must be rust-proofed and waterproofed.
2. Install and seal, applying marine-grade polyurethane sealant. Use high-strength stainless steel bolts with anti-loosening washers to lock the air conditioner base to the reinforced beam. Perform the first waterproof seal.
3. Refrigerant copper tubing must be securely fixed, with pre-installed anti-vibration bends. All cables must be threaded through flame-retardant corrugated conduits and properly secured. Terminal blocks must be crimped using hydraulic crimping tools and insulated.
4. Perform a high-vacuum evacuation (at least 45 minutes) on each system independently, followed by precise refrigerant charging.
Travel Trailer Ac – Your Ultimate Action Advice
1. Experience with large bus or luxury trailer conversions. Employed structural engineers and certified electricians and refrigeration technicians.
2. Deep involvement in the design: You need to clearly define your needs (number of residents, extreme climate zones, noise reduction requirements, etc.) and repeatedly communicate with engineers regarding the plan, layout, and budget.
3. Upon completion, archive complete structural drawings, electrical schematics, refrigeration piping diagrams, equipment manuals, and warranty documents. For Travel Trailer Ac design and installation, visit www.busclima.com or contact busclima@kingclima.com for further technical support.
Summary: Installing a rooftop air conditioner on an oversized trailer is a comprehensive upgrade to its “infrastructure” (structure, electrical). The goal is not just to obtain air conditioning, but to achieve a safe, reliable, efficient, and intelligent cabin environment control system. Please treat this project with the highest standards and professionalism.
