CTC Installation Kit Reversing Valve Package Solar Recovery

Description

Complete installation package from CTC designed for docking and solar recovery against ground source heat and boreholes. By integrating solar heat with the heat pump's brine circuit, excess heat from solar collectors can effectively recharge the borehole during the summer months and relieve the system during operation, which lowers operating costs and extends the life of the system. The package is delivered complete with a 230V motor-driven 3-way diverter valve, necessary pipe fittings, 22 mm compression fittings and a detailed installation manual for quick and safe installation.

Key Benefits

• Complete installation kit: Contains diverter valve, pipe sections and connection fittings for seamless integration.
• High operational reliability: Robust valve housing in corrosion-resistant brass and copper pipe with Kvs value of 2.8 for optimal flow.
• Standardized electric operation: 230V actuator controlled directly via the heat pump's regular automation.
• Energy-efficient recharge: Optimizes the regeneration of the energy well in the event of excess sunlight.

Areas of application

• Borehole recharge (Passive regeneration): Conducts excess solar heat from solar collectors directly into the borehole or ground loop during the summer months to restore the ground temperature for winter.
• The brine circuit in ground source heat pumps: Mounted on the collector loop (brine circuit) in CTC ground source heat pumps to automatically switch between normal operation and solar charging.
• Hybrid and combination systems: Used in systems that combine solar thermal energy (solar collectors) with heat pump technology for maximum total annual performance factor (SCOP/COP).
• Direct brine preheating: Raises the temperature of the incoming brine on sunny days in spring and autumn, which reduces the compressor's electricity consumption during operation.
• Unloading and system protection: Helps to dump excess heat from the solar circuit to the ground when the accumulator tank is fully charged, which prevents overheating and boiling in the solar collector system.
