Cooling & Heating Solutions for Farms, Hotels & Plants
Description
Product Description
Combined air-source heat pump designed for ultra-large demand of water consumption, heating and cooling. Based on the Extreme Enthalpy DWL series and SRM special module units, it supports multi-unit combination of the same series or mixed connection across series. Each system can combine up to 10 modules for flexible capacity expansion of heating capacity. The product includes:
- Heating&Cooling Module(RMDRN-DWL combination)
- Hot Water Module(RMDRN-SRM series)
- Hot water module rated hot water output: 3120L/h–7140L/h, suitable for ultra-large water demand of 600–1800 people.
- Heating module maximum heating capacity: 550kW, suitable for heating&cooling demand of super-large buildings. It adopts a core master-slave integrated design. Failure of a single module will not affect the operation of the entire system.
Core advantage
- Integrated master-slave design: any slave unit can switch to master. Failure of the main module does not affect system operation, greatly improving equipment stability.
- Supports multi-unit combination and cross-series mixed connection; allows phased investment and gradual expansion to meet long-term water, heating and cooling expansion needs.
- Module graded start function significantly reduces starting current, minimizes grid impact, and ensures safe operation of other electrical equipment in the same area.
- Module equalization function monitors each compressor in real time, automatically balances running hours and extends overall service life.
- Multi-compressor design per unit with dual backup operation; if one compressor fails, others continue running to guarantee uninterrupted supply.
- Compact unit size allows transport via freight elevators and forklifts without large cranes, enabling easy on-site handling, positioning and flexible installation.
Usage scenario
Applicable scenarios for ultra-large-scale hot water, heating and cooling demand: Large industrial parks, universities with tens of thousands of students, large general hospitals, high-end cultural tourism&resort cities, large factories, high-speed rail stations/airports, urban commercial complexes, etc.
Q&A
Q1: The modular unit can combine up to 10 modules. Will the overall operating efficiency decrease after combination?
A1: No, it will not decrease. Jubang modular units adopt a new Venturi distributor and multiple electronic expansion valves for precise temperature control. After combination, the refrigerant is evenly distributed and the heat exchange efficiency remains unchanged. In addition, the module equalization function enables efficient coordinated operation of each unit to ensure overall system efficiency.
Q2: For phased investment and expansion, is it necessary to re-commission the entire system when adding new modules later?
A2: There is no need to re-commission the whole system. Jubang modular units are plug-and-play. Later additional modules only need to be connected to the original system via pipelines and circuits. The equipment will automatically identify and integrate them into unified system management, realizing seamless expansion with simple commissioning.
Q3: In ultra-large scenarios, will the modular units start simultaneously when power is restored after a power outage, causing a huge impact on the power grid?
A3: They will not start at the same time. The unit is equipped with a module graded start function. When power is restored, each module will start in batches and stages, greatly reducing the overall starting current, avoiding impact on the power grid and ensuring normal operation of other electrical equipment in the park or building.
Q4: In ultra-large-scale scenarios, does daily equipment maintenance require shutdown? Will it affect normal hot water/heating/cooling supply?
A4: No overall shutdown is required. Each module of the modular unit is an independent operating unit. During maintenance, a single module can be shut down separately while others operate normally, ensuring continuous supply in ultra-large-scale scenarios. Maintenance is convenient without affecting normal use.
