A workstation environment regulation method considering human thermal sensation

Abstract

This invention proposes a workstation environment control method that considers human thermal sensation. It aims to study the human physiological thermal regulation system, propose the laws governing human thermal response, and thus accurately predict human thermal sensation, creating a low-carbon and efficient thermal environment control method that meets human thermal comfort requirements. This method is applicable to indoor office workstation environment control. The method includes parameter acquisition to obtain local microenvironment parameters and skin temperatures at 4-5 body parts; thermal sensation analysis to determine the overall thermal sensation of the current environment based on the current local skin temperature; and environmental control to determine the direction and measures of environmental control based on the thermal sensation evaluation results. If the thermal sensation is within the allowable range, no correction is needed. Otherwise, the microenvironment of areas far from the neutral environment is corrected, and the direction and magnitude of local microenvironment and background environment control are determined. Traditional environmental control methods are divided into central air conditioning for overall thermal environment control and personalized end-point adjustment at workstations.

Description

Technical Field

[0001] This invention belongs to the field of workstation environment control technology, specifically relating to a workstation environment control method that takes into account human thermal sensation. Background Technology

[0002] Skin temperature is an important physiological parameter reflecting the level of heat exchange between the human body and the environment, and it is closely related to human thermal sensation. Skin temperature varies in different parts of the body in hot and cold environments. For example, the skin temperature of the head increases in a warmer environment, while the skin temperature of the legs and feet decreases in a colder environment. The different skin temperatures in different parts of the body are the result of the body's own physiological regulation in response to environmental stress. Previous calculations of average skin temperature obtained by weighted averaging across different body parts did not differentiate between the sensitivity of different parts of the body to hot and cold environments. Therefore, the calculation results could not accurately reflect human thermal sensation.

[0003] Therefore, considering the differences in human physiological responses under hot and cold environments, this invention proposes a method for calculating the average skin temperature that reflects human temperature sensation, providing more accurate thermal sensation results. Based on the thermal sensation evaluation results, it also provides an optimal approach to thermal environment regulation that satisfies both maximum thermal comfort and minimum energy consumption. Summary of the Invention

[0004] In view of this, the present invention provides a workplace environment control method that takes into account human thermal sensation, in order to solve the problem in the prior art where average skin temperature is calculated by weighted averaging of various parts of the body, without distinguishing the sensitivity of different parts of the body to hot and cold environments. The calculation results cannot truly and effectively reflect human thermal sensation.

[0005] The technical solution adopted in this invention is as follows:

[0006] A method for controlling the work environment that takes into account human thermal sensation includes the following steps:

[0007] Step 1: Based on the collected workstation environmental characteristic parameters and personnel clothing parameters, determine the current temperature status of the environment, and adjust the central air conditioning system according to the temperature status until the indoor air temperature meets the requirements;

[0008] Step 1 specifically includes the following steps:

[0009] Step 1.1: Calculate the thermal perception evaluation index PMV, as shown in the following formula:

[0010] PMV = (0.303e -0.036M +0.0275)×[MW-3.05(5.733-0.007(MW)-P a )-0.42(MW-58.2)-0.0173M(5.867-P a -0.0014M(34-t)a ) - 3.96×10 -8 f cl ((t cl + 273) 4 -(t mr + 273) 4 ) - f cl h c (t cl - t a )] = f(x1, x2, x3, x4, M, I cl );

[0011] In the formula, M represents the human body metabolic rate, W represents the external output work of the human body, Pa represents the partial pressure of water vapor around the human body, ta represents the air temperature around the human body, fcl represents the clothing area factor of the human body, tcl represents the clothing surface temperature, tmr represents the mean radiant temperature, h c represents the convective heat transfer coefficient, x1 represents the indoor air temperature, x2 represents the indoor air humidity, x3 represents the indoor air velocity; x4 represents the indoor mean radiant temperature; the human body metabolic rate M takes 1.1 met, representing the activity level of office workers with slightly active sedentary periods, and the clothing thermal resistance I cl is determined according to the clothing situation of office workers;

[0012] Step 1.2: Based on the calculation result of PMV, judge the cold and hot state of the current environment;

[0013] In Step 1.2, the determination rules for the cold and hot state are as follows:

[0014] If the PMV calculated value satisfies PMV < -1, it is judged as a cold deviation environment;

[0015] If the PMV calculated value satisfies -1 ≤ PMV < -0.5, it is judged as a neutral and slightly cold environment;

[0016] If the PMV calculated value satisfies -0.5 ≤ PMV ≤ +0.5, it is judged as a neutral environment;

[0017] If the PMV calculated value satisfies +0.5 < PMV ≤ +1, it is judged as a neutral and slightly hot environment;

[0018] If the PMV calculated value satisfies PMV > 1, it is judged as a hot deviation environment.

[0019] Step 1.3: Adjust the central air conditioning system according to the cold and hot state until the indoor air temperature meets the requirements.

[0020] The specific content of Step 1.3 includes:

[0021] When the environment is cold and deviates from the ambient temperature, PMV < -1, let PMV = -1, calculate the required indoor air temperature x1, determine the supply air temperature based on the air volume of the central air conditioning system, and adjust the supply air temperature value until the indoor air temperature meets the requirements.

[0022] If the environment is thermally deviating from the environment, and PMV>1, let PMV=+1, calculate the required indoor air temperature x1, determine the supply air temperature based on the air volume of the central air conditioning system, and adjust the supply air temperature value until the indoor air temperature meets the requirements.

[0023] If the environment is neither cold nor hot and the central air conditioning system deviates from the ambient temperature, and -1≤PMV≤+1, the central air conditioning system will not be adjusted.

[0024] Step 2: Based on the determined hot and cold conditions, calculate the average skin temperature of the personnel, and obtain the personnel's thermal sensation based on the average skin temperature;

[0025] In step 2, the average skin temperature of the person performing the calculation is calculated according to the following rules:

[0026] Based on the differences in local skin temperature of people in hot, cold and neutral states under the same typical winter or summer clothing, the distribution values ​​of local skin temperature under the condition of neutral human thermal sensation and the differences in skin temperature of each part under thermal state changes are obtained.

[0027] In order to identify body parts that are greatly affected by the environment, body parts with differences exceeding the algebraic average of all body parts are selected as local thermal regulation target areas. The weighting coefficient of the change proportion of the area to be regulated is obtained by mathematical statistics, and the weighted average of the area to be regulated is calculated as the average skin temperature of cold or heat sensation. The statistical relationship between average skin temperature and thermal sensation is established, and an empirical formula reflecting the average skin temperature of cold or heat sensation is obtained to predict thermal sensation.

[0028] Step 2 specifically includes:

[0029] If the environment is neutral to cool, -1 ≤ PMV < -0.5, then the formula for calculating the average skin temperature of the cold-sensing novel system is:

[0030] t csk =0.28t sk,H +0.23t sk,M +0.18t sk,F +0.16t sk,C +0.15t sk,J

[0031] In the formula, t sk,H Indicates foot skin temperature, in °C; t sk,M This indicates the skin temperature of the shins, in °C; t sk,F Indicates the skin temperature of the forecourt, in °C; t sk,CIndicates the lower arm skin temperature, °C; t sk,J Indicates the upper arm skin temperature, °C.

[0032] The human thermal sensation TSV evaluation value is:

[0033] TSV = 0.28t csk -8.86

[0034] In the formula, t csk Indicates the calculated value of the new average skin temperature in a slightly cold environment, °C.

[0035] If the environment is neutral to slightly hot, +0.5 < PMV ≤ +1, then the formula for calculating the new average skin temperature for warm sensation is

[0036] t wsk = 0.15t sk,H + 0.17t sk,E + 0.19t sk,F + 0.14t sk,I + 0.20t<� sk,C + 0.15t sk,J

[0037] In the formula, t sk,H Indicates the foot skin temperature, °C; t sk,E Indicates the back of hand skin temperature, °C; t sk,F Indicates the front thigh skin temperature, °C; t sk,I Indicates the neck skin temperature, °C; t sk,C Indicates the lower arm skin temperature, °C; t sk,J Indicates the upper arm skin temperature, °C.

[0038] Then the human thermal sensation TSV evaluation value is:

[0039] TSV = 0.76t wsk -24.58

[0040] In the formula, t wsk Indicates the calculated value of the new average skin temperature in a slightly hot environment, °C.

[0041] Step 3: Determine whether the environment meets the comfort level requirements according to the thermal sensation calculation result. If not, determine the regulation plan for the workstation microenvironment according to the thermal sensation calculation result, and perform controllable adjustment on the workstation microenvironment.

[0042] The specific content of the said Step 3 includes:

[0043] If the environment is a thermoneutral environment, -0.5 ≤ TSV ≤ +0.5, the local workstation environmental control system does not adjust;

[0044] If TSV < -0.5, determine the body parts that need adjustment based on the test results of skin temperature at each part, and determine whether to turn on the heater at the bottom of the workstation or the heating of the workstation tabletop based on the optimal combination of minimum heating energy consumption and TSV comfort.

[0045] If TSV > 0.5, determine the body parts that need adjustment based on the test results of skin temperature at each part. Based on the optimal combination of minimum cooling capacity and ventilation energy consumption and TSV comfort, determine whether to turn on the cooling plate under the workstation, the cooling plate on the workstation table, or the workstation air supply system.

[0046] The preferred combination based on the lowest cooling capacity and ventilation energy consumption and TSV comfort specifically includes:

[0047] S1: Set the objective function to minimize cost f1(x) i ) and maximize performance f2(x) i );

[0048] S2: Design variable x i Adjusting heating / cooling capacity locally at the workstation;

[0049] S3: Select f1(x) i The primary optimization objective is to minimize energy consumption, f2(x) i As a secondary objective, set the constraint |f2(x) i )|≤0.5;

[0050] S4: Use gradient descent to minimize f1(x) i ), and simultaneously satisfy |f2(x) i The constraint condition is |≤0.5;

[0051] S5: Based on steps S1-S4, obtain the initial f1(x) i After optimizing the solution set, sensitivity analysis is performed on different adjustment schemes, that is, for the initial optimized solution scheme x i Determine f1(x) i f2(x) and f2(x) i Sensitivity to changes in f1(x) to identify changes in f1(x) i f2(x) and f2(x) i Schemes with significant sensitivity {x} i In these solution sets, prioritize those that satisfy f1(x). i Secondly, it satisfies f2(x) i The proposed solution will be the final decision.

[0052] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0053] 1. In this invention, considering the differences in human physiological responses under hot and cold environments, a method for calculating the average skin temperature reflecting human hot and cold sensations is proposed, providing more accurate thermal sensation results. Based on the thermal sensation evaluation results, an optimal approach to thermal environment regulation that satisfies both maximum thermal comfort and minimum energy consumption is provided.
