Abstract

The invention discloses a cold chain compartment space fixed-point cooling device based on magnetic refrigeration. The device comprises a compartment body, wherein a space support is arranged in the compartment body, an air coolant conduit penetrates through the space support, exhaust holes are formed in the space support into an array, and a corresponding electromagnetic gas valve is arranged beside each exhaust hole; the two ends of the air coolant conduit penetrate through the top of the compartment body, the two ends of the air coolant conduit are arranged in the same cooling water bath fixed to the top of the compartment body, and a magnetic refrigeration component is arranged on the top of the compartment body; a plurality of temperature sensors are distributed on the space support, and a main controller is also arranged on the top of the compartment body and connected with the temperature sensors through wires. By the adoption of the device, fixed-point cooling can be achieved in the cold chain compartment, and local temperature control delay is avoided.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to the technical field of space fixed-point cooling devices. Background technique [0002] Air temperature regulation is just needed in industry and life, especially in the industrial field, such as the temperature control in the cold chain transport compartment, which has strict requirements. However, the air temperature adjustment has obvious hysteresis, which is manifested in the temperature gradient of the air temperature in the space. The current air-conditioning technology adopts single-source cooling, that is, the position of the cooling point is constant, and the temperature conducts through heat conduction or convection, resulting in Temperature control hysteresis. Contents of the invention [0003] The purpose of the present invention is to solve the problem of temperature control hysteresis in the existing air-conditioning technology, and propose a f...
