TERRA DX 5 HCUA

Product catalog summary
Overview: The document provides technical specifications and operational details for the Ochsner TERRA DX 5 HCUA heat pump, which utilizes direct geothermal extraction for monovalent heating systems using the ground as a heat source.
Specifications: The heat pump has dimensions of 1289x600x680 mm, a weight of 185 kg, and a hydraulic connection size of 1 1/4 inch. It operates on a three-phase, 400V, 50Hz power supply with a maximum operating current of 4.00 A and a starting current of 27.00 A (13.50 A with soft start). The sound power level is 41.30 dBA.
Performance: The heating output varies with different operating points, with a maximum of 6.20 kW at standard point E4/W35 and a COP of 4.80. The condenser is a plate heat exchanger made of stainless steel, with a maximum refrigerant operating pressure of 30 bar.
Refrigerant Circuit: The system uses R407C refrigerant with a charge range of 3.4-5.5 kg. The compressor is a scroll type with a speed of 2900 rpm.
Evaporator: The tube evaporator has a recommended number of circuits of 3-4, with a maximum of 5 circuits, each 75 m in length.
Geothermal Collector: The O-Tube Pro collectors are pre-filled with nitrogen and include a leakage indicator. They require specific spacing and routing plans for installation.
Recommended Accessories: Includes heat pump buffer tanks, DHW tanks, external plate heat exchangers, and electric immersion heaters.
Conditions and Requirements: The document outlines the required extraction surface and conditions for different soil types, specifying maximum extraction capacities and connection lengths.
Energy Efficiency: The product is rated A+++ for low temperature (35°C) and A++ for medium temperature (55°C), with SCOP values ranging from 3.42 to 5.37 depending on conditions.
Installation Notes: The document provides guidelines for the installation of geothermal collectors, including spacing, routing, and labeling requirements.
