Problems solved by technology

In this kind of refrigeration process, it is necessary to use fluid to carry cold, and the thermal conductivity of fluid is much lower than that of solid, which greatly limits the speed of circulation, making the total refrigeration power smaller

Abstract

The invention relates to an indoor temperature ferroelectric refrigeration machine, in particular to a full-solid-state indoor temperature ferroelectric refrigeration machine based on thermal switches. The machine achieves heat regeneration through ferroelectric materials. The full-solid-state indoor temperature ferroelectric refrigeration machine based on the thermal switches comprises N ferroelectric refrigeration pieces which are alternatively inserted in the N+1 thermal switches which are the same in size, the thermal switch on the outmost side is connected with a high-temperature heat source and a low-temperature heat source, and the N ferroelectric refrigeration pieces carry out control according to the specified field increasing and field decreasing sequence and correspondingly control the N+1 thermal switches to be on and off so as to achieve refrigeration. The full-solid-state indoor temperature ferroelectric refrigeration machine based on the thermal switches has the beneficial effects of being quite compact in structure, high in efficiency and low in noise.

Description

technical field [0001] The invention relates to a room-temperature ferroelectric refrigerator, in particular to an all-solid-state room-temperature ferroelectric refrigerator based on a thermal switch and using ferroelectric material heat recovery (or called ferroelectric cold storage AFR). Background technique [0002] The traditional and widely used refrigeration method is mechanical vapor compression cycle refrigeration. The refrigerant used in this refrigeration technology will destroy the ozone environment above the atmosphere and have a greenhouse effect, and the current alternative refrigerants also have a large greenhouse effect index and explosiveness, which not only has low refrigeration efficiency, but also seriously affects Energy utilization and human living environment. [0003] It is very important to research and develop new refrigeration methods that are energy-saving, safe and environmentally friendly. As a new refrigeration method, room temperature ferro...
