| Technology description including background system | The NIBE S735 is an intelligent inverter-controlled exhaust air heat pump with an integrated hot water heater, providing heating, hot water and ventilation efficiently and economically. It provides large savings as it automatically adapts to your home’s heating needs. Operational Principle: This exhaust air heat pump has an integrated fan and a water heater provided with corrosion protection in the form of copper, enamel or stainless steel. There is an integrated immersion heater used as an additional heater when it becomes really cold outside. Energy is recovered from the ventilation air and supplied to the heat pump, which significantly reduces the energy consumption. The device ventilates the house, supplies heat and produces domestic hot water. S735 is intended for low-temperature dimensioned radiator circuits and/or underfloor heating. This product is suitable in houses or equivalent, both in new-builds and as a replacement. unit and it works based on the floating condensing principle. The principle of how this type of pump operates in buildings is presented in general terms by the drawings in this section. (A) S735 ventilates the house and supplies it with both hot water A and room heating. (B) The warm room air is drawn into the air duct system. (C) The warm room air is fed to S735. (D) The air is released when it has passed S735. The air temperature has then dropped since S735 has extracted the energy in the air. (E) Outdoor air is brought in, either directly into the house or via E a supply air module. (F) Air is diverted from rooms with outdoor air devices to rooms F with exhaust air valves. (G) Heated air is blown out into rooms with supply air valves. (H) Air is transferred from rooms with supply air valves to rooms H with exhaust air valves. Detailed information for the product, manuals, ect. are available on NIBE's webpage: https://www.nibe.eu/ The declared unit of this life cycle assessments is the rated heat output of the heat pump at average climate as reported in the product energy label, where applied standrads are EN14825, EN 16147 and EN12102-1. This is eque to 1 unit of finish product. At NIBE AB in Markaryd, Sweden several different products are manufactured therefore production is divided into different production segments e.g. facility for air to water heat pumps, facility for ground source pumps and facility for exhaust air heat pumps. These facilities focus mainly on product assembly, quality testing and packaging of approved products. The components and assemblies in these facilities might be classified as purchased or internally manufactured. Certain parts used in the products are internally manufactured at NIBE AB’s production site. Examples include cabinet sides, different metal plates, pressure vessels, frames, etc. Heat pump manufacturing is a complex process involving many different steps, but generally described the process could be simplified to a few major steps: Production of internally manufactured components from purchased raw materials, Pre-assembly of specific pre-assembly groups, Testing of the refrigeration unit (High pressure testing), Filling in the Refrigerant, Final assembly, Final product testing, Packaging, Distribution. |
