Abstract
The utility model relate to a kind of can be according to the control system that can control collecting system leaving water temperature of feature change at sunshine period collecting system water outlet temperature setting.System is comprised of ARM single-chip microcomputer, data storage, temperature sensor and water pump, in system, ARM single-chip microcomputer is connected with data storage, temperature sensor and constant temperature water inlet water pump, the output water temperature of the collecting system that data storage is preserved the from date in each season, the strong and weak sunshine-duration node of each every day in season and each time point are corresponding, the temperature sensor measurement collecting system delivery port water temperature of system, controls constant temperature intake pump duty by the leaving water temperature value of relatively storing and the delivery port temperature value of sensor measurement.The utility model is by providing a kind of intensity of sunshine time point and the mode of the output water temperature definition of corresponding collecting system in each that records in season, reaches the not object of leaving water temperature definition in the same time of change solar thermal collection system, thereby utilizes to greatest extent solar energy.
Description
Technical field
The utility model relates to the control system that a kind of collecting plate output water temperature of solar heat pump central hot-water system is controlled, be specifically related to a kind of can be according to solar heat water controller and the corresponding control method thereof of feature change at sunshine period collecting system leaving water temperature.
Background technology
The method that at present solar heat pump central hot-water system obtains hot water from solar thermal collection system is mainly: the delivery port of the collecting system of solar water heating system is provided with cooling-water temperature sensor, collecting system absorbs after solar radiation, in collecting system, water temperature rises, when the water temperature in collecting system reaches the temperature of setting, solar heat pump central hot-water system sends control instruction, circulating pump is inputted cold water in collecting system, and the cold water of injection is pressed into the original hot water of collecting system the attemperater supplying water to user.Current solar energy central heat pump hot-water system substantially all adopts fixed temperature value to the output water temperature of collecting system, the attemperater of sending into water supply with the hot water of assurance steady temperature value, part control system allows to arrange an output water temperature value and reaches the object that output water temperature is adjusted.
Above system all lacks in actual applications to be judged the feature at sunshine in various places each seasons, this for sunshine not enough and sunshine abundance situation be all unfavorable for that system the most effectively obtains solar energy.In the environment of deficiency at sunshine, when the energy that collecting system solar radiation obtains and the energy of radiation loss reach balance, collecting system cannot be by water temp. heating to assigned temperature toward contact, collecting system cannot be obtained lower than the water of specifying leaving water temperature and sends into the attemperater that user supplies water, system cannot obtain the hot water that solar radiation produces; And in the environment of abundance at sunshine, the hot water that can be heated to higher temperature originally also can only be admitted to attemperater in the output water temperature value of appointment.Therefore, cannot realize solar energy utilization ratio maximizes.This patent provides a kind of solar energy central heat-pump hot-water control device and corresponding control method by judgement feature at sunshine in season change solar thermal collection system leaving water temperature can solve the problems referred to above raising solar energy utilization ratio.
Summary of the invention
The purpose of this utility model is to make the collecting system output water temperature of solar energy central heat pump hot-water system regulate the output water temperature of collecting system according to the quantity of heat production feature of various places solar energy in each in season, thereby makes system have the maximized control characteristic of solar energy utilization ratio.
In order to realize the object of foregoing invention, design technology project of the present utility model is: system is by ARM single-chip microcomputer, data storage, temperature sensor and water pump form, ARM single-chip microcomputer and data storage in system, temperature sensor and constant temperature water inlet water pump connect, data storage is preserved the from date in each season, the output water temperature of the collecting system that the strong and weak sunshine-duration node of each every day in season and each time point are corresponding, the temperature sensor measurement collecting system delivery port water temperature of system, by the leaving water temperature value of relatively storing and the delivery port temperature value of sensor measurement, control constant temperature intake pump duty.Collecting system output water temperature corresponding to each time period of in store system default in data storage, the host computer outside permission system is simultaneously according to each seasonal characteristic change control time point of various places and corresponding collecting system output water temperature.
In system, ARM single-chip microcomputer judges whether the host computer outside system has the modification of sending that the set point information of data storage is set, if there is modification, turn to carry out and revise and replace the settings in memory, otherwise the corresponding settings of delivery port water temperature and the temperature value of collecting system delivery port of current time in single-chip microcomputer read memory; System is made comparisons the delivery port water temperature of acquisition and output water temperature setting, if the delivery port water temperature obtaining is greater than the output water temperature setting of reading, start constant temperature water inlet water pump, otherwise host computer sends to revise data is set: in order to guarantee that system there will not be the ceaselessly phenomenon of start-stop constant temperature water inlet water pump, in native system, adopt to subtract the value of 3 ℃ with delivery port water temperature settings and compare, extend the service life of water inlet water pump.
Implementation result
The beneficial effect that the utility model is implemented is: utilize native system the leaving water temperature of collecting plate to be set in conjunction with solar energy feature in each of different regions in season, thereby reach the object of the heat that maximum using solar energy system provides as far as possible.
