Description

A kind of air-conditioning system control device based on pressure sensor

Technical field

The invention belongs to Air-condition system control field, relate in particular to a kind of air-conditioning system control device based on pressure sensor.

Background technology

Delay and the unstable state characteristic of room conditioning load: in air-conditioning technical, for keeping temperature and humidity condition certain in room that refrigeration duty or the thermic load of air-conditioning system are provided to the cold providing in room or heat, refrigeration duty comprises sensible heat load and latent heat load.Human body heating has unstable state characteristic, belongs to allostatic load in summer, belongs in the winter time unstable state thermal source.The radiation load of solar radiation and dense population can not form the refrigeration duty of air-conditioned room immediately, but absorbed, reflection, heat release, absorb again by room inner surface and various furnishings, reflect again, heat release again, in heat transfer process repeatedly, by accumulation of heat, the exothermic effects of room and furnishings, the radiation components of hankering is gradated as convection current composition, be converted into refrigeration duty, this process need regular hour.But the impact that this partial radiation heat produces human thermal comfort, less than postponing, can affect the sendible temperature of human body immediately.

Often there is the situation that personnel assemble suddenly in Waiting Lounge and ENTRANCE at high ferro or subway, due to interpersonal radiation heat transfer and interpersonal not smooth apart from less ventilation, the sendible temperature of people in gathering crowd can instantaneous improve, and it is very scorching, uncomfortable that people can feel.But because the unstable state heating of gathering of people needs a period of time could affect the air themperature in whole room, be arranged on the variation that the air-conditioning system temperature controller of side wall cannot be measured human body ambient air temperature in time, also cannot measure the generation of the scorching sense of human body, so uncontrollable air conditioning terminal blowing device makes a response in time----strengthen in time for cold in summer, reduce in time in the winter time heating load, to reduce the sendible temperature of human body in gathering crowd, improve human thermal comfort degree.Due to the existence of this situation, the air-conditioning system of the high ferro of high investment, high standardized construction or the Waiting Lounge of subway and ENTRANCE but often can not effectively make passenger feel comfortably cool when passenger needs most.

Summary of the invention

The object of this invention is to provide a kind of air-conditioning system control device based on pressure sensor, to overcome prior art above shortcomings.

The object of the invention is to be achieved through the following technical solutions:

A kind of air-conditioning system control device based on pressure sensor, comprise Air-condition system control device, described Air-condition system control device is connected with solar radiation sensor, outdoor temperature sensor, outside humidity sensor, indoor temperature transmitter, indoor humidity sensor, pressure sensing ground cushion and some air-conditioning ends, described air-conditioning end is connected with the fast controller of air-conditioning draught fan three and air-conditioner water system motor-driven valve, and the fast controller of described air-conditioning draught fan three is connected with Air-condition system control device with air-conditioner water system motor-driven valve.

Further, described pressure sensing ground cushion is the common thickening ground cushion of band by some pressure sensors.

Further, between described pressure sensor, horizontal and vertical interval is all not more than 300mm.

Further, described air-conditioning end is the ceiling type air conditioner unit of being furnished with frequency converter.

Beneficial effect of the present invention is: 1, applicability is wide, can utilize existing system to carry out transformation and upgrade: the present invention can be installed additional at the Waiting Lounge of existing high ferro or subway and ENTRANCE place, install additional simple and easy to do, do not increase main equipment, the Waiting Lounge to high ferro or subway and ENTRANCE place air-conditioning system are not changed, applicability is wide, can carry out transformation and upgrade for existing building, and new building does not more have problems.In addition, the present invention also can be used on ticket lobby, the large hospital intensive place of personnel's discontinuity such as hall, movie theatre entrance of registering, and is with a wide range of applications.

2, intelligent degree is high: the present invention is provided with outdoor intensity of solar radiation, temperature and moisture sensors and pressure sensing ground cushion, and be provided with the parameter of Air-condition system control device pick-up transducers, according to default control program, air conditioning terminal blowing device is scientifically controlled.

3, good energy-conserving effect: in summer, in order to improve the human thermal comfort degree of personnel compact district, operation of air conditioner manager often reaches maximum by air conditioner system air blast amount and chilled water motor-driven valve, and design temperature is set to below 25oC.But the gathering of people at the Waiting Lounge of high ferro or subway and ENTRANCE place is intermittent, in the time that personnel amount is few, just produce energy waste with maximum for the air-conditioning system of cold, the operation of low design temperature.The present invention can working pressure sensing ground cushion survey crew closeness, in the time that personnel's closeness is normal, and the temperature controller of the similar common air-conditioning system of controller action, system is with the conventional state operation of similar common air-conditioning system.In the time that personnel's closeness of passing through transfinites, Air-condition system control device of the present invention can move with maximum cooling capacity in summer according to the signal controlling air-conditioning end of pressure sensing ground cushion.In the winter time, in the time that personnel's closeness of passing through transfinites, Air-condition system control device of the present invention can move with minimum heating load according to the signal controlling air-conditioning end of pressure sensing ground cushion.

4, improve human comfort: the phenomenon that the present invention can locate the instantaneous gathering of personnel to Waiting Lounge and the ENTRANCE etc. of high ferro or subway is made a response in time, strengthen in time for cold in summer, reduce in time in the winter time heating load, to reduce the sendible temperature of human body in gathering crowd, improve human thermal comfort degree.
