  1. 1. Capacity Control of Residential Heat Pump Heating Systems

    Author : Fredrik Karlsson; Energiteknik (ET).; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy efficiency; variable-speed; air-source; performance; hydronic heating system; ground-source; heat pump; defrost; optimisation; circulator; capacity control;

    Abstract : Heat pumps used for space and sanitary hot water heating of residential buildings are increasingly popular in northern Europe. As they compete with other heating equipment and in order to limit the environmental impact of their use, it is very important that heat pumps are energy efficient. READ MORE

  2. 2. Experimental Investigation of Refrigerant Charge Minimisation of a Small Capacity Heat Pump

    University dissertation from Stockholm : KTH

    Author : W. Primal D. Fernando; KTH.; [2007]

  5. 5. Apply heat pump systems in commercial household products to reduce environmental impact How to halve the electricity consumption for a household dishwasher

    University dissertation from Karlstads universitet

    Author : Peder Bengtsson; Karlstads universitet.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; household appliance; electricity consumption; heat pump; environmental impact; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : In the household appliance industry, heat pump systems have been used for a long time in refrigerators and freezers to cool food, and the industry has driven the development of small, high-quality, low-price heat pump components. In the last few decades, heat pump systems have been introduced in other household appliances, with the express purpose of reducing electricity consumption. READ MORE
