Patent number: 7185506Abstract: Reversible vapor compression system including a compressor (1), an interior heat exchanger (2), an expansion device (6) and an exterior heat exchanger (3) connected by means of conduits in an operable relationship to form an integral main circuit. A first device is provided in the main circuit between the compressor and the interior heat exchanger, and a second device is provided on the opposite side of the main circuit between the interior and exterior heat exchangers to enable reversing of the system from cooling mode to heating mode and vice versa. The first and second device for reversing of the system include a first and second sub-circuit (A respectively B) each of which is connected with the main circuit through a flow reversing device (4 and 5 respectively). Included in the system solution is a reversible heat exchanger for refrigerant fluid, particularly carbon dioxide. It includes a number of interconnected sections arranged with air flow sequentially through the sections.Type: GrantFiled: August 31, 2001Date of Patent: March 6, 2007Assignee: Sinvent ASInventors: Kåre Aflekt, Einar Brendeng, Armin Hafner, Petter Nekså, Jostein Pettersen, Håvard Rekstad, Geir Skaugen, Gholam Reza Zakeri

Patent number: 7131291Abstract: A compression refrigeration system includes a compressor (1), a heat rejector (2), expansion device (3) and a heat absorber (4) connected in a closed circulation circuit that may operate with supercritical high-side pressure. The refrigerant charge and component design of the system corresponds to a stand still pressure inside the system which lower than 1.26 times the critical pressure of the refrigerant when the temperature of the whole system is equalized to 60° C. Carbon dioxide or a mixture of a refrigerant containing carbon dioxide may be applied as the refrigerant in the system.Type: GrantFiled: July 26, 2002Date of Patent: November 7, 2006Assignee: Sinvent ASInventors: Kåre Aflekt, Arne Jakobsen, Jostein Pettersen, Geir Skaugen, Armin Hafner, Petter Nekså, Håvard Rekstad, Gholam Reza Zakeri

Patent number: 6931880Abstract: A method of defrosting of a heat exchanger (evaporator) in a vapor compression system including, downstream of a heat exchanger (evaporator) (3) to be defrosted, at least a compressor (1), a second heat exchanger (condenser/heat rejecter) (2), and an expansion device (6) connected by conduits in an operable manner to form an integral closed circuit. The heat exchanger (3) to be defrosted is subjected to essentially the same pressure as the compressor's (1) discharge pressure. Thus, the heat exchanger (3) is defrosted as the high-pressure discharge gas from the compressor (1) flows through to the heat exchanger, giving off heat to the heat exchanger (3). In the circuit, in connection with the expansion device (6) a first bypass loop 23 with a first valve (16?), is provided.Type: GrantFiled: August 31, 2001Date of Patent: August 23, 2005Assignee: Sinvent ASInventors: Kåre Aflekt, Einar Brendeng, Armin Hafner, Petter Nekså, Jostein Pettersen, Håvard Rekstad, Geir Skaugen, Gholam Reza Zakeri

Publication number: 20040103681Abstract: Method for defrosting of a heat exchanger (evaporator) in a vapor compression system including, beyond a heat exchanger (evaporator) (3) to be defrosted, at least a compressor (1), a second heat exchanger (condenser/heat rejecter) (2) and an expansion device (6) connected by conduits in an operable manner to form an integral closed circuit. The heat exchanger (3) to be defrosted is subjected to essentially the same pressure as the compressor's (1) discharge pressure whereby the heat exchanger (3) is defrosted as the high-pressure discharge gas from the compressor (1) flows through to the heat exchanger, giving off heat to the said heat exchanger (3).Type: ApplicationFiled: July 21, 2003Publication date: June 3, 2004Inventors: Kare Aflekt, Einar Brendeng, Armin Hafner, Petter Neksa, Jostein Pettersen, Havard Rekstad, Geir Skaugen, Gholam Reza Zakeri
