Refrigeration cycle device and heat exchange unit

Abstract

The invention discloses a refrigeration cycle device and a heat exchange unit, and relates to the technical field of air conditioners, the refrigeration cycle device comprises the heat exchange unit, a guide element, a transmission device and a ventilation device, the heat exchange unit is composed of a transmission part, a thermoelastic element and a fixing assembly, and the thermoelastic element is made of elastic shape memory alloy; the transmission part is used for changing the relative position between the fixing assemblies so that the state of the thermoelastic element can be changed between a loose state and a tensioning state, and the transmission device is used for transmitting received rotating power to the transmission part so that the transmission part can move relative to the guiding element. And the thermoelastic element is periodically changed between refrigeration and heat dissipation so as to achieve the purpose of adjusting the environment temperature. The shape memory alloy is adopted as a medium for temperature adjustment, the structure is simple, design is ingenious, the heat exchange efficiency is high, and meanwhile the problem of environmental pollution existing in a traditional gas compression refrigeration technology is solved.

Description

technical field [0001] The present application belongs to the technical field of air conditioning, and in particular relates to a refrigeration cycle device and a heat exchange unit arranged in the refrigeration cycle device. Background technique [0002] All over the world, the electricity consumed by refrigeration accounts for more than 15% of the global electricity, which produces a large amount of carbon emissions every year, and with economic development and global warming, this ratio will become higher and higher. In addition, today's most widely used vapor compression refrigeration technology has achieved a Carnot cycle theoretical efficiency close to 40-45% after a century of development. However, most of the refrigerants used in vapor compression refrigeration are not environmentally friendly. For example, the best refrigerant liquids are toxic (amino chemicals are still used in industrial production) or cause ozone depletion and greenhouse effects (freon and hydrof...
