Continuous variable temperature constant temperature system and method

Abstract

The present invention belongs to the constant temperature technology field, and especially relates to a continuous variable temperature constant temperature system. The system comprises a heating module, a constant temperature water tank, a cooling module, a monitoring module, a control module and a host module. The heating module, the cooling module and the monitoring module are connected with the control module, the monitoring module, the heating module and the cooling module are connected with the constant temperature water tank, and the host module is connected with the control module. The present invention further provides a constant temperature method. At a constant temperature environment, the system changes a traditional passivity to initiative to perform initiative temperature compensation of the constant temperature system to better keep the constant temperature environment; when heating and temperature rising are performed, the system rapidly and effectively reaches a setting temperature through an algorithm; a cooling device is added, a similar heating algorithm is employed when cooling is required to allow the system to better reduce to an assigned temperature so as to allow the system to be more improved; and moreover, in order to satisfaction of the experiment requirements, the constant under different temperatures in an assigned range can be set.

Description

technical field [0001] The invention belongs to the technical field of constant temperature, and in particular relates to a constant temperature system and method capable of continuously variable temperature. Background technique [0002] At present, more and more contact-type constant temperature systems (such as constant temperature water tanks) are used in experiments and scientific research. Such systems generally use constant temperature in a liquid (mostly distilled water) environment for related operations. In the current constant temperature system, when it is necessary to heat up the temperature, it often occurs that the temperature after heating is higher than the set temperature, and then drops back to the set temperature. In the experiment, it is often necessary to keep the temperature constant for a long time at a certain temperature , so as to measure the relevant physical quantities. In the process of constant temperature, due to the gradual loss of heat cause...

Problems solved by technology

[0003] Aiming at the deficiencies and shortcomings in the prior art, the present invention proposes a new method to solve such problems. According to the temperature that needs to be reached, the heating device is automatically turned off by the heat relationship, so that the temperature can be steadily raised to the specified temperature. In order to maintain the specified temperature The temperature is constant for a period of time, and the method of active temperature supplementation is adopted. We use the method of controlling the power of the heating device to supplement the heat lost naturally, so as to better keep the system constant at the specified temperature, etc. The specific technical solutions are as follows:
