Description
Affiliated technical field
The present invention relates to a kind of device for detecting air conditioner energy effect ratio, refer in particular to the Energy Efficiency Ratio real-time detection apparatus of room air conditioner.
Background technology
The Energy Efficiency Ratio data in China air-conditioning market are relatively more chaotic at present, and the authentication of Chinese air-conditioning Energy Efficiency Ratio is not also put into effect, and country does not also have relevant standard, therefore bad measurement.The data that producer propagates on market all are the data of producer from newspaper basically, these data all are to set under the operating mode, get in the laboratory by room heat balance test device, and the efficiency value that the consumer shows air-conditioning producer is also felt to suspect, what the consumer more needed is the situation that air-conditioning is contained in their family operation, and need and not know the data that also also uncomprehending laboratory drew a consumer.A kind of air-conditioning Energy Efficiency Ratio real-time detection apparatus proposes at this point.
Summary of the invention
For the Energy Efficiency Ratio to air-conditioning detects in real time, for providing air-conditioning, the consumer is contained in the Energy Efficiency Ratio data of their family operation, the present invention proposes a kind of device for detecting air conditioner energy effect ratio, form by Sensor section, operation part, storage area, control section, several parts in display part, and can combine itself and air-conditioner controller together, not only reduce volume, also can directly utilize the data in the air-conditioner controller, avoid the repeated use of device, reduce cost.
The technical solution adopted for the present invention to solve the technical problems is: device for detecting air conditioner energy effect ratio of the present invention is made up of several parts in Sensor section, operation part, storage area, control section and display part.Sensor section mainly is made up of temperature sensor, humidity sensor, air flow sensor, watt transducer, and temperature sensor comprises EAT sensor and leaving air temp sensor; Humidity sensor comprises air intake humidity sensor or air-out humidity sensor; Air flow sensor refers to the wind speed button position or the air quantity control position of air-conditioner controller; Watt transducer refers to voltage and current measured value, compressor of air conditioner running status, the frequency when compressor of air conditioner moves of compressor of air conditioner; Operation part refers to the parameter value of Sensor section be carried out data correction, the input parameter modified value; Storage area deposits data and computing formula, the computing formula of surface-type heat exchanger and the computing formula of air-conditioning Energy Efficiency Ratio of soft air parameter in; Control section calculates the real time data of air-conditioning Energy Efficiency Ratio and the data of day part according to the data and the computing formula of Sensor section, operation part and storage area; The display part shows the real time data of air-conditioning Energy Efficiency Ratio and the data of day part according to the calculated value of control section.
The detection principle is as follows: can obtain the thermic load value Q of indoor apparatus of air conditioner and the electric power W of compressor of air conditioner according to measuring with calculating, its ratio is air-conditioning Energy Efficiency Ratio COP value, i.e. COP=Q/W just.Thermic load value Q is by the computing formula Q=q of surface-type heat exchanger
m(h

2Enthalpy for air-out.q
mValue obtains by wind speed button position or the air quantity control position of detecting air-conditioner controller, this is because general air-conditioner controller can both be controlled the wind speed of indoor apparatus of air conditioner, for fixed indoor apparatus of air conditioner, the certain air quantity of wind speed is certain, so wind speed button position or air quantity control position by air-conditioner controller, promptly know the size of air quantity, that is to say for fixed indoor apparatus of air conditioner, the wind speed button position or the air quantity control bit of air quantity and air-conditioner controller are equipped with fixing funtcional relationship, so can be the wind speed button position of air-conditioner controller or air quantity control position as air flow sensor, we have just known airflow value by wind speed button position or the air quantity control position of detecting air-conditioner controller, wherein the wind speed button position is meant the wind speed control to the air-conditioner controller input, and the air quantity control position is meant the wind speed control to blower fan of air-conditioner controller output.h
2Value and h
1Value is by the humiture value of the turnover wind of indoor apparatus of air conditioner, according to the data of soft air parameter with computing formula obtains or the wet figure of enthalpy of humid air checks in, the humiture value of the turnover wind of indoor apparatus of air conditioner can be by indoor apparatus of air conditioner the Temperature Humidity Sensor of turnover wind measure, also can obtain temperature value by the turnover wind-warm syndrome degree sensor measurement of indoor apparatus of air conditioner, obtain a humidity value with a humidity sensor measurement, by calculating another humidity value, this is because of under the surface-type heat exchanger in indoor apparatus of air conditioner stable condition, between the turnover wind-warm syndrome humidity certain functional relation ε is arranged
2=1-(t

S1), ε wherein
2The expression contact coefficient is certain to its value of fixed surface-type heat exchanger, t
G1The dry-bulb temperature t of expression air intake
S1The wet-bulb temperature of expression air intake, t
G2The dry-bulb temperature of expression air-out, t
S2The wet-bulb temperature of expression air-out.The electric power W of compressor of air conditioner can obtain by voltage U and the electric current I of measuring compressor of air conditioner, i.e. W=UI; Under the normal voltage, voltage when moving owing to it for fixed non-frequency compressor of air conditioner is constant substantially, its resistance is also constant, its electric current is also constant, electric power W during its operation is also just constant, so can obtain the electric power size by detecting running status running status as watt transducer; Under the normal voltage, because the frequency in its when operation is relevant with the electric power size, the frequency in the time of also can be operation is as watt transducer for frequency converting air-conditioner compressor, so the frequency identification when moving just can be known the electric power size.
The invention has the beneficial effects as follows, detect the air-conditioning Energy Efficiency Ratio in real time, the consumer knows that promptly air-conditioning is contained in the situation of their family operation, finally reaches the purpose of energy savings.
