Centralized plug & play aerothermal system for air conditioning and DHW production
System integrating a heat recovery exchanger with recirculation pump, 3-way valve and intelligent management for domestic hot water management.
Centralized Aerothermal System
Aerothermal air-conditioning system with continuous simultaneous DHW production using heat recovery. It has three operating modes, optimizing total thermal consumption by avoiding independent systems for each need and optimizing space, control and energy efficiency.
Benefits
- Simultaneous air conditioning and DHW
- Optimized global thermal production
- Lower contracted power per user
- Heat Recovery
- Lower installation and maintenance cost
- Plug & Play System
- Lower carbon footprint
- Decarbonization of the residential sector
- Less occupied space
Energy efficiency and design
- EC axial fan with integrated curved nozzle
- Cu-Al coils
- Polyurethane, Blygold and Cu-Cu protections
- SIEMENS programmable AQUAMATIX electronic control and CLIMATIX HMI terminal
- DHW tank made of 316L stainless steel with expansion vessel and electronic recirculation pump
- Hydraulic connections
- KWE Heat Pump + KWD DHW Hydraulic Group
Integral Solution: 3 operating modes
- Combined generation in cooling mode
- Combined generation in heating mode
- DHW generation
