Title:
多段冷凍サイクルを用いた温度調節装置及びそれを用いた温度調節方法
Document Type and Number:
Japanese Patent JP7174502
Kind Code:
B2
Abstract:
Provided is a temperature control device capable of controlling an object to be cooled at a set temperature in response to the entire control temperature range even when a temperature control range of the object to be cooled is wide. The temperature control device according to the present invention comprises at least a high temperature side refrigeration cycle 21a and a low temperature side refrigeration cycle 21b. The high temperature side refrigeration cycle and the low temperature side refrigeration cycle each have a circulation circuit (3) including a compressor (4), a condenser (5), an expansion valve (6), and an evaporator (7) arranged therein to circulate a refrigerant, wherein: the condensation of a refrigerant at the low temperature side refrigeration cycle is performed by a refrigerant of the high temperature side refrigeration cycle; an inverter-controllable compressor is used as a compressor of the device; an electronic expansion valve is used as an expansion valve of the device; the set temperature of a circulation liquid is divided into several parts in advance; according to each region, an operation frequency of the compressor and an open degree of the electronic expansion valve are parameterized to be set; and the operation frequency of the compressor and the open degree of the electronic expansion valve are automatically controlled on the basis of a parameter according to the set temperature of the circulation liquid.
