Problems solved by technology

However, since the temperature of the above-mentioned secondary air is controlled by the temperature of the primary air, if the temperature of the primary air flowing in from the air inlet 20 is low, it may happen that the temperature of the secondary air in the outlet duct 21 cannot be raised. It is difficult to stably control the temperature of the secondary air in the outlet pipe 21 within the required temperature range

Abstract

A refrigeration air dryer outputs dehumidified air dehumidified by a cooling operation using a low-temperature refrigerant after the temperature thereof has been raised by exchanging heat with a high-temperature refrigerant at a reheater. The refrigeration air dryer includes a temperature sensor which detects the temperature of secondary air in the outlet pipe, valve means which adjusts the flow rate of the dehumidified air or the flow rate of the refrigerant flowing through the reheater, and a temperature controller which adjusts the flow rate of the dehumidified air or the flow rate of the refrigerant by controlling the valve means based upon the detected temperature detected by the temperature sensor, thereby maintaining the temperature of the secondary air at a constant level.

Description

technical field [0001] The invention relates to a refrigerated air dryer, in particular to a refrigerated air dryer which cools the compressed air to condense the moisture in the compressed air to dehumidify the compressed air. Background technique [0002] In an air pressure system using an air compressor such as a solenoid valve or a cylinder, in order to prevent failure caused by moisture contained in the compressed air supplied to it, it is necessary to remove the moisture in the compressed air in advance. Always use a refrigerated air dryer. Moreover, on the refrigerated air dryer, cooling and dehumidifying the low-temperature compressed air will cause dew condensation in the air duct on the secondary side of the air dryer. To prevent this dew condensation, it is necessary to control the The temperature of the compressed air at the outlet is used to heat up the dehumidified compressed air again. [0003] image 3 Shown is the circuit of the refrigerant system and the ...
