GMSW 11 PLUS

Product catalog summary

Overview: The document provides technical specifications and guidelines for the Ochsner GMSW 11 PLUS geothermal heat pump, which uses brine as a heat source. It is designed for monovalent heating systems and complies with the Machinery Directive.

Appliance Data: The heat pump has dimensions of 1150x400x650 mm, a weight of 169 kg, and a hydraulic connection size of 1 1/4 inch. The casing is available in Tiger white and grey (RAL 7016).

Specifications: The system operates on a 3-phase, 400V, 50Hz power supply with a maximum operating current of 7.40 A and a starting current of 52.00 A (26.00 A with soft start). The sound power level is 48 dBA, and the sound pressure level is 40 dBA at 1 m distance.

Heating Mode Performance: The heat pump's performance varies with different operating points:

B0/W35: Heating output of 10.30 kW, power consumption of 2.05 kW, and COP of 5.00.
B0/W50: Heating output of 9.30 kW, power consumption of 3.10 kW, and COP of 3.00.
B0/W60: Heating output of 8.80 kW, power consumption of 3.70 kW, and COP of 2.40.

Condenser and Evaporator: Both are plate heat exchangers made of stainless steel 1.4301. The condenser has a maximum refrigerant operating pressure of 45 bar and a heat transfer medium pressure of 6 bar. The evaporator operates with a brine medium and has a maximum pressure of 12 bar.

Refrigerant Circuit: Utilizes R410A refrigerant with a charge of 2.25 kg. The compressor is a scroll type with a speed of 2900 rpm.

Recommended Accessories: Includes heat pump separating cylinders, DHW tanks, 3-way switching modules, and brine collector sets for shallow laying.

Performance Curves: The document provides energy consumption and SCOP values for low and medium temperature settings, indicating efficiency ratings of A++.

Installation Guidelines: Details on the collection shaft, including dimensions and materials, are provided for optimal installation.

Extraction Capacity: The document outlines maximum specific extraction capacities for various soil conditions and installation methods, such as shallow laying, deep trench laying, and geothermal probes.

Sizing Recommendations: Pressure loss guidelines are provided for connection lines and brine circuits, with maximum allowable losses specified.
