Problems solved by technology

In the case of such a large temperature change, the user needs to constantly set the operating status of the HVAC equipment to meet the daily needs, which brings inconvenience to people's life, and this control method has a hysteresis, which is often felt by the user. Only when the surrounding temperature is uncomfortable, will the operating status of the HVAC equipment be reset, which reduces the user's comfort and has room for improvement.

Embodiment 1

[0060] When the temperature T2 of the current unit time A of the indoor environment is less than or equal to the set temperature T1, control the HVAC equipment to enter the heating mode;

[0061] When the temperature T2 of the current unit time A of the indoor environment is greater than the set temperature T1, the HVAC equipment is controlled to enter the cooling mode; otherwise, the HVAC equipment is controlled to maintain the preset working mode.

Embodiment 2

[0063] When the temperature T2 of the indoor environment is less than the difference between the set temperature T1 and the temperature difference threshold ΔT for mode switching, control the HVAC equipment to enter the heating mode;

[0064] When the temperature T2 of the indoor environment is greater than or equal to the difference between the set temperature T1 and the mode switching temperature difference threshold ΔT and is less than or equal to the sum of the set temperature T1 and the mode switching temperature difference threshold ΔT, control the HVAC equipment to maintain the preset working mode;

[0065] When the temperature T2 of the indoor environment is greater than the sum of the set temperature T1 and the mode switching temperature difference threshold ΔT, the HVAC equipment is controlled to enter the cooling mode. Wherein, the mode switching temperature difference threshold ΔT may be a temperature difference that a human body can feel.

Embodiment 3

[0067] When the temperature T2 of the current unit time A of the indoor environment is less than or equal to the set temperature T1;

[0068] Obtain the current temperature slope k2 information of the temperature T2 of the current unit time A of the indoor environment;

[0069] Find the current instruction information corresponding to the current temperature slope k2 information from the preset correspondence between the temperature slope k2 information and the instruction information; the temperature slope k2 information includes positive coefficient temperature slope k2 information, negative coefficient temperature slope k2 information and Non-positive and non-negative coefficient temperature slope k2 information; instruction information includes positive coefficient temperature slope k2 execution information corresponding to positive coefficient temperature slope k2 information, negative coefficient temperature slope k2 execution information corresponding to negative coeffic...

Abstract

The invention discloses an energy-saving heating and ventilation control method and system, and relates to the technical field of building equipment control. The energy-saving heating and ventilationcontrol method and system solve the problem that when the temperature change is relatively large, an user needs to continuously set the operation state of heating and ventilation equipment so as to meet the daily requirements. The energy-saving heating and ventilation control method comprises the following steps that after the heating and ventilation equipment receives the set temperature T1 of auser and starts up, the temperature T2 of the current unit time A of the indoor environment is obtained every other preset time t, and according to the comparison condition between the temperature T2of the current unit time A and the set temperature T1, a preset refrigerating mode or heating mode of the heating and ventilation equipment is controlled to be opened and closed. According to the energy-saving heating and ventilation control method and system, the working modes of the heating and ventilation equipment can be automatically switched according to the change of temperature so as to achieve the life intelligentization and simplification of people, convenience is brought to the life of people, and the comfort level of the user is improved.

Description

technical field [0001] The invention relates to the technical field of building equipment control, in particular to an energy-saving HVAC control method and system thereof. Background technique [0002] HVAC is an integral part of construction. In the subject classification, the full name is heating, gas, ventilation and air conditioning engineering, including: heating, ventilation, and air conditioning. Today, as HVAC equipment is becoming more and more popular, people have higher and higher requirements for the intelligent operation of HVAC equipment. [0003] At present, people can set the running state of HVAC equipment through various controllers, such as remote controllers, wired controllers, centralized controllers, and even computer software, mobile phone software, etc., so the set running state is fixed. For example, set running cooling, set temperature 20 degrees or set running heating, set temperature 27 degrees, etc. However, in certain regions and during cert...
