Rapid heating and cooling system

Abstract

The invention provides a rapid heating and cooling system, and relates to the technical field of laboratory temperature control. The rapid heating and cooling system based on a heating and cooling system device comprises a temperature sensing module, the temperature sensing module is in signal connection with a digital frequency conversion module, and the digital frequency conversion module is insignal connection with a refrigerating module and a heating module; a modular process of the rapid heating and cooling system is as follows: 1) inputting the temperature required by a laboratory through the temperature sensing module; 2) calculating the temperature difference between the target temperature and the actual temperature in the laboratory through the temperature sensing module, and then transmitting the calculation result to the digital frequency conversion module; and 3) sensing the temperature difference calculated by the temperature sensing module through the digital frequency conversion module so as to change the power supply frequency of refrigerating and heating units of the refrigerating module and the heating module, thereby controlling the refrigerating and heating speeds. According to the invention, the laboratory temperature adjustment is fast, the constant temperature state is good, and the temperature adjustment is intelligent and soft.

Description

technical field [0001] The invention relates to the technical field of laboratory temperature control, in particular to a rapid heating and cooling system. Background technique [0002] PCR laboratory is also called gene amplification laboratory. PCR is the abbreviation of polymerase chain reaction (Polymerase Chain Reaction). It is a molecular biology technique used to amplify specific DNA fragments, which can be regarded as special DNA replication outside the body. Through the DNA gene tracking system, the virus content in the patient's body can be quickly grasped, and its accuracy is as high as nanometers. Whether there is an abnormal change in function can timely judge which type of antiviral drug is most suitable for the patient, judge the efficacy of the drug, and provide a reliable test basis for clinical treatment. [0003] In the prior art, most of the laboratory temperature control devices in the PCR laboratory are air conditioners, which cannot quickly change t...
