Embodiment Construction

[0012] Referring to the accompanying drawings, a casing type regenerator device includes a first stainless steel tube 1, and a tube cap 4 with a through hole is provided at both ends of the first stainless steel tube 1, and the through hole of the tube cap 4 is connected to There is a third stainless steel pipe 3, and the third stainless steel pipe 3 passes through the first stainless steel pipe 1, and the second stainless steel pipe 2 is arranged on the outer wall of the first stainless steel pipe 1. The shell-and-tube heat exchanger is a heating type shell-and-tube heat exchanger. The diameter of the first stainless steel tube 1 is larger than that of the second stainless steel tube 2 . The diameter of the second stainless steel pipe 2 is larger than that of the third stainless steel pipe 3 . The outer walls of the first stainless steel pipe 1 , the second stainless steel pipe 2 and the third stainless steel pipe 3 are provided with insulation layers.

Abstract

The invention belongs to the field of heat regenerators and discloses a sleeve type heat regenerator device. The sleeve type heat regenerator device comprises a first stainless steel tube, tube caps with through holes are arranged at the two ends of the first stainless steel tube, third stainless steel tubes are connected to the through holes of the tube caps and penetrate through the first stainless steel tube, and second stainless steel tubes are arranged on the outer wall of the first stainless steel tube. The sleeve type heat regenerator device has the advantages that the structure is simple, the workload is low, the material consumption is small and the cost is saved. The gas inlet temperature of a compressor is increased, the gas content of the compressor is increased, the phenomenon that frictional loss of parts of the compressor is excessively large because of liquid hammering and low oil temperature is effectively avoided, and the phenomena that a low pressure cavity of the compressor frosts, the compressor gives an alarm about low pressure and the operation of a heat pump system is influenced are effectively avoided on the condition that the outdoor environment temperature is low. The sleeve type heat regenerator device is simple in structure, low in failure rate and safe and reliable in operation.

Description

technical field [0001] The invention belongs to the technical field of regenerators, in particular to a casing type regenerator device. Background technique [0002] In order to ensure the safe operation of the compressor, it is required that the suction temperature of the compressor is higher than the evaporation temperature, that is, there is an appropriate degree of superheat between the evaporation temperature and the suction temperature of the compressor. Risk of damage to components, especially compressor valves. [0003] At the same time, if the suction pressure is too low, it will cause the compressor to lock at low pressure and affect the operation of the compressor. Most of the existing regenerator devices place the high-pressure and high-temperature heat pump working fluid and the low-temperature and low-pressure heat pump working fluid pipelines together in a container, and realize the heat transfer process through mutual conduction, so as to achieve the desired...
