Fig. 1 structural representation of the present invention.
Wherein: 1 trough type solar heat-collector, 2 storage heaters, 3 auxiliary thermal sources, 4 absorption refrigeration air-conditionings, 5 absorption type refrigeration air-conditionings, 6 circulating pumps, 7 electric T-shaped valve I, 8 sun tracking systems, 9 electric T-shaped valve II.
The specific embodiment
A kind of solar energy of the present invention directly drives absorption type air conditioning system, comprises the trough type solar heat-collector 1, storage heater 2, auxiliary thermal source 3, absorption refrigeration air-conditioning 4 and the absorption type refrigeration air-conditioning 5 that are connected on the circulation line.Circulation line is provided with circulating pump 6.Trough type solar heat-collector 1 is provided with sun tracking system 8; Sun tracking system 8 comprises rotary decelerating motor, obliquity sensor and controller; Obliquity sensor is used to detect the angle variable quantity that trough type solar heat-collector 1 rotates, and controller is used for rotateing in place according to obliquity sensor angles fed back variable quantity control rotary decelerating motor-driven trough type solar heat-collector 1.
Trough type solar heat-collector 1 is parallel with a path and path and circulation line junction and is provided with electric T-shaped valve I 7, and storage heater 2 is provided with electric T-shaped valve II 9 with the circulation line junction, and controller signals connects electric T-shaped valve I 7 and electric T-shaped valve II 9.Obliquity sensor adopts AT205 series obliquity sensor.
The rotary decelerating motor adopts no gap rotary decelerator.
Use because trough type solar heat-collector 1 is middle temperature, so take up an area of for a short time, easy for installation, whole heat collector mainly is divided into foundation, structure stand, condenser, vacuum tube, annex etc.All component adopts module to install, and can produce the subassembly product of standard in factory, when Product transport behind the job site, as long as through having gone basic prefabricated work, can advance factory's construction and installation early stage.
Absorption type refrigeration air-conditioning 5 and absorption refrigeration air-conditioning 4 be through accepting the stable heated medium of heat source side, converts desired heat of output and cold to through self the operation of working mechanism, and refrigeration air-conditioner pushes to use side through medium pump with cold.Absorption type refrigeration air-conditioning 5 pushes to use side and heat accumulator tank through medium pump with heat, takes the thermal medium in the heat holding vessel voluntarily by the end user.
It is low that system of the present invention has energy consumption compared to other type air-conditioning, pollutes for a short time, safeguards simply, and the life-span is long, to the usage degree advantages of higher of environment.Modular combination is used in integral installation, can split combination arbitrarily to the combination of refrigeration-heating air-conditioner according to user's requirement.Crucial pipeline component adopts welding procedure, has guaranteed the security and the air-tightness of pipeline, has promoted reliability, has reduced the working service cost in later stage.Use solar energy as main drive energy, and have the accumulation of energy functional device, optimize and utilized solar energy simultaneously, avoided the waste of general solar energy utilization system again.
Can satisfy fully at solar energy under the prerequisite of heat of refrigeration unit needs, the solar radiation heat energy of collecting is stored in the middle of the storage heater 2 through heated heat-conducting medium, to be ready for use on the use not enough time of the no sun or solar energy.
When running into when being not suitable for opening trough type solar heat-collector 1; Controller identification current environment is also made judgement; Start electric T-shaped valve I 7; System provides heat by storage heater 2 and auxiliary thermal source 3, then medium is sent into absorption type refrigeration air-conditioning 5 and absorption refrigeration air-conditioning 4, circulates through row heat delivery next time once more through medium pump then.
When if current weather uses trough type solar heat-collector 1 can not satisfy the work of absorption type air-conditioner separately, open electric T-shaped valve I 7, control is selected to use storage heater 2 or auxiliary thermal source 3 this moment, replenishes use.
Perhaps whole device is in stopped status when shutdown; When controller was experienced environment temperature and is lower than 5 ℃ (can set), controller force start medium pump took place with the situation of avoiding frozen pipe; Move triple valve simultaneously; Make the media flow that exists in the heat collector,, open auxiliary thermal source 3 when opening medium pump and promote these system pipeline temperature and stop until design temperature if when temperature is lower than 0 ℃ again.
The advantage that solar energy directly drives refrigeration is not use fossil ability heating and cooling working medium such as natural gas; And avoided used heat to utilize the unsettled shortcoming of heat supply of formula again through the combination of heat collector and storage heater 2; So solar energy directly drives consumption and pollution that refrigerating plant has been avoided traditional energy; The output of the stable energy is provided again, and only the pipeline portions in system has used power devices such as pump, and other the air-conditioning system energy consumption of comparing reduces greatly.
Obliquity sensor adopts AT205 series obliquity sensor.AT205 series obliquity sensor is to measure carrier static tilt angle with respect to the horizontal plane, through the measure static change in gravitational acceleration, converts angle change to, measures the inclination angle value with the angle of pitch (x) and roll angle (y) expression.
Employing has the silicon micro mechanical sensor and the high performance microprocessor of unique advantage; A/D converter through high-speed, high precision; With original acceleration of gravity signal input iir digital filter; The noise of balancing a survey signal and the relation of data updating rate, the stability of raising measurement data is guaranteed measured real-time property and precision.The power interface of product and communication interface have adopted the electromagnetic compatibility processing, guarantee reliability of products.Sensor has functions such as gamma correction, quadrature adjustment, zero correction partially, address number setting, wave filter setting, data updating rate setting, HEX and the selection of ASCII output format, and the user can select to use flexibly.Product angle range is ± 75 degree.If realize measuring, can get in touch with factory at bigger angular range.The products-hardware interface is respectively TTL, RS-232, RS-422, RS-485, CAN, and the software interface agreement is taken into account intuitive and security, is easy to user's operation and use.AT205 series inclinator belongs to high-end typical products in the inclination angle product of 0.1 degree accuracy class, in the inclination angle of same precision grade, have best performance.The rotary decelerating motor adopts no gap rotary decelerator.
The above only is the preferred implementation of this patent; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the patent art principle; Can also make some improvement and replacement, these improvement and replacement also should be regarded as the protection domain of this patent.
