Description
Technical Field
The present invention relates to a temperature control method, and more particularly, to a cabin temperature control method considering an ambient temperature.
Background
For ships and marine equipment, traditional cabin temperature adjusting equipment such as air conditioners, boilers and fan heaters, the temperature control method does not consider the ambient temperature outside the cabin, only can set the target temperature of the cabin, easily generates the condition of large temperature difference inside and outside the cabin, is not beneficial to the health of crews and equipment maintenance, increases resource consumption and aggravates environmental pollution. This is particularly the case when ocean-going vessels are sailing across latitudes.
The cabin temperature control method provided by the invention adds consideration to the environmental temperature. The method can automatically calculate and adjust the target temperature of the cabin according to the ideal temperature in the cabin and the allowable temperature difference inside and outside the cabin and by sensing the environmental temperature through the comprehensive environmental temperature sensor, so that the temperature difference inside and outside the cabin is kept within the allowable temperature difference, thereby being beneficial to the health of crews and the maintenance of equipment, reducing the consumption of resources and lightening the environmental pollution.
For example, it is comfortable for the user to set the air conditioning setting at 20 ℃ when the cabin exterior temperature is 30 ℃. When the temperature outside the cabin rises to 35 ℃, although the indoor temperature is more comfortable at 20 ℃, the indoor and outdoor temperature difference is increased, the indoor and outdoor heat exchange is stronger, the indoor temperature loss is quicker, the air conditioner compressor is frequently started, the load and the power consumption of the compressor are increased, and the Freon consumption is increased to bring greater load to the environment. In addition, the cold air directly blown by the air conditioner is usually lower than 16 ℃ but not the target temperature of 20 ℃, and the human body is more likely to suffer from diseases, namely air conditioning diseases, after being contacted with low-temperature air for a long time, which runs counter to the aim of building comfortable temperature.

Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1 and 2, a method for controlling temperature of a chamber in consideration of ambient temperature includes the steps of:
s1, setting the ideal indoor temperature T0, setting the allowable indoor and outdoor temperature difference △ T;
s2: measuring indoor temperature T1 and outdoor temperature T2 in real time, and calculating T2-T1 in real time;
S3：
if the absolute value of T2-T1 is less than △ T, the temperature in the control room is adjusted towards the direction of T0;
if T2-T1 is not less than △ T, the temperature in the control room is adjusted towards the direction of T2- △ T;
if T2-T1 is less than or equal to- △ T, the temperature in the control room is adjusted towards the direction of T2+ △ T;
s4: s2 through S4 are repeated.
The following improvements may also be made: at S1, the method further includes setting an upper limit temperature T3, and at S3, if T1> T3, the cabin temperature is reduced to T3 or less. At S1, a lower limit temperature T4 is set, and at S3, if T1< T4, the temperature in the control room is increased to T4 or higher.
The device for realizing the method comprises a temperature control system for regulating the temperature of the indoor space, wherein the temperature control system is connected with a P L C system (1) for controlling the temperature control system to heat or refrigerate, the P L C is also connected with an indoor temperature sensor (3) placed in the indoor space and an outdoor temperature sensor (2) placed in the outdoor space, and the P L C system (1) inputs T0 and △ T through a control station (4) or a remote controller (5).
For example, the ideal temperature T0 is set to 20 ℃, allowing a temperature difference △ T of 10 ℃.
If the indoor temperature T1 is 25 degrees and the outdoor temperature T2 is 32 degrees initially, the temperature difference is T2-T1 is 7 degrees < △ T, and the temperature control system starts to adjust the indoor temperature toward T0 being 20 degrees, during the adjustment, the indoor and outdoor temperature difference starts to increase until the indoor temperature is 22 degrees (assuming that the outdoor temperature does not change at this time), the temperature difference is 10 degrees < △ T, and according to the regulation, the target indoor temperature needs to be changed to T2- △ T being 22 degrees, and if the outdoor temperature drops by 2 degrees or 3 degrees at this time, the target temperature may still be changed to T0 being 20 degrees, and similar discussions can be made for the case of T1< T2 initially.
The method does not change the working principle of the equipment, only is an optimized mode for setting the temperature, and can be added into a control system as a control mode.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
