Description
Technical field
The invention belongs to agricultural mechanical field, the ventilating dehumidifier tool that particularly a kind of plastic tunnel and greenhouse are used, ventilating dehumidifier for greenhouse.
Technical background
At present, the vegetables production development of the northern area of China canopy chamber is rapid.Plastic vegetable greenhouse and livestock and poultry floriculture greenhouse are most important production facilities.Because the north of china in winter low temperature time long (about 5 months), day and night temperature big (15 ℃--20 ℃), existing daylight type canopy is indoor owing to irrigate water evaporates, plant leaf surface water evaporates, factors such as indoor/outdoor temperature-difference dewfall can be in any more the indoor temperature of canopy, humidity for a long time.Wherein, the situation of humidity＞85% is very common.And the canopy room air does not circulate the content of carbon dioxide and oxygen and irrational distribution.The crop growth development environment mainly contains luminous environment, temperature environment, humidity environment, gaseous environment, soil environment five big factors.The present domestic overwhelming majority's agriculture canopy chamber is because economics dictate also can only solve illumination and the insulation problem in producing winter.Because crops fear low temperature freezing-disaster, normally ventilation, humidity and air ambient that canopy is indoor are very poor, very easily cause crops and livestock and poultry, floral crops diseases, influence its normal growth and grow.Therefore, the humidity environment and the gaseous environment of solution canopy chamber become the task of top priority of industrialized agriculture production technology.
Summary of the invention
The purpose of this invention is to provide and a kind ofly with electric blowing machine the fresh low humidity air of open air, canopy chamber is sent into indoorly, the ventilating dehumidifier for greenhouse of the wet turbid air of displacement is the low agricultural machinery of a kind of high-performance price.
Ventilating dehumidifier for greenhouse of the present invention, it is characterized in that by be located at breeze fan on the canopy room floor, therewith the air-supply passage that is connected of breeze fan and control device, the detector that is connected of control device and the exhaust blower that is located at top, canopy chamber are formed therewith.
Be provided with heater in the described air-supply passage.
Described control device is switches set, single board computer or controller.
Described detector comprises thermometer, moisture meter, carbon dioxide analyser.
Described switches set comprises pressure fan power switch, exhaust blower power switch, heater power source switch.
But described heater is a temperature regulating heater.With carbon fibre material as calandria.
Described breeze fan and exhaust blower adopt energy-efficient switched reluctance machines.
Described controller is by temperature, humidity, carbonic acid gas set-point input circuit, the comparison circuit that is connected of set-point input circuit and thermometer, moisture meter, carbon dioxide analyser therewith, the control signal output circuit that is connected of comparison circuit connects into therewith.This control signal output circuit is connected with breeze fan, exhaust blower, heater.
The invention provides and a kind ofly with electric blowing machine the fresh low humidity air of open air, canopy chamber is sent into indoorly, the ventilating dehumidifier for greenhouse of the wet turbid air of displacement is the low agricultural machinery of a kind of high-performance price.For accelerating replacing velocity, reduce time of exchanging gas, open the induced-draught fan of identical performance indications synchronously at opposite side.Thereby reach the dual purpose of interior humidity environment of controlling chamber and gaseous environment.Final realize that canopy room light photograph, humidity, temperature, gas content, moisture control etc. can regulate and control according to the production law of different crops or livestock and poultry, flowers, guarantee high-quality, the high yield of agricultural product and animal products, and then realize the industrialized agriculture production modernization.Characteristics of the present invention are: by manual operation or automation control mode, regulate and control by the needs of plant and livestock and poultry, production of flowers and plants rule.When indoor humidity need be regulated, open switch, start calandria and give, exhaust blower.Make the cold air of the outer drying of its suction chamber.And carry out preheating by calandria in by the way of ajutage at it.Make its temperature with indoor temperature required send into after identical indoor.For guaranteeing the quick and room pressure balance of dehumidifying, exhaust blower is discharged indoor original turbid humid gas from opposite side, increases indoor gas circulation and humidity conversion.The operator can determine the length of heating-up temperature height and air-supply (air draft) time by moisture meter, thermometer, carboloy dioxide analysis meter, stops the scavenging period that dehumidifies in good time.Also can carry out automation control and form, thereby realization is to the control of indoor production environmental factor by calculator.
Advantage of the present invention is:
1, advanced technology, the cost performance height:
Be starting point with the current daylight canopy chamber condition of generally using, select for use advanced carbon fibre material to make calandria, energy-efficient switched reluctance machines drive fan also realizes that two-shipper is synchronous, in the hope of reaching energy savings, and thermal efficiency height, reliable and stable and non-maintaining.When conditions permit, add calculator and necessary sensor to illumination, temperature, humidity, gas ingredients and soil composition carry out comprehensively monitoring, improve the scientific and technological level of canopy chamber.Help the peasant to step the first step of modernized agricultural production with less input.
2, reasonable in design, handled easily:
The present invention is not high to outside conditional request, removes outdoor of canopy and needs power supply.Can divide in use with three kinds of control modes: i.e. manually control: the user is according to the dehumidifying of taking a breath of detected parameters Switching Power Supply; Automatically control: after the user opens machine, the equipment Automatic Detection and Control; Based Intelligent Control: calculator is dynamically controlled indoor environmental condition by the production management program.
3, the function material benefit, be easy to expansion: major function is: ventilation changes indoor oxygen and gas concentration lwevel; Regulate humidity, guaranteeing ventilation dehumidifying under the indoor temperature condition of canopy; Regulate temperature: the control wind pushing temperature regulates the room temperature.
Expanding function: if on hardware, improve, be easy to the roller shutter machine, gobo, soil moisture is controlled automatically; With the growth conditions compiled program of different plants, realize Based Intelligent Control.In sum, ventilating dehumidifier for greenhouse is a kind of novel agricultural machinery.It can be used for current widely used daylight canopy chamber and livestock and poultry greenhouse.Realize the greenhouse technology upgrading with less input.Require more harsh chiefeconomic crop to create conditions for producing to environmental condition.
