The breif introduction of JINYI Solar energy hot water system
The JINYI solar energy central water heating system is made up by solar collector, tank, controller system, electromagnetic valve, circulating pump, appurtenances and so on. Its principle is that collector make cold water become warm and then circulate to the tank by circulating pump, and our controller reach:
Set the temperature to electric heat --- supplies the hot water in constant temperature;Temperature difference circulation --- enhance the heating efficiency;The pipeline circulation--- can get the hot water no waiting;The preventing frostbite--- normally uses in winter.The entire system function automatically, safely, maintains conveniently. Because of the simple structure, the system can be installed nimbly according to customer's demand. We also install electric heating in the tank. So you can also have hot water when it's rainy, achieving electric heating auxiliary, microcomputer intelligence controller to guarantee user can get hot water 24 hours all year.
The types of JINYI solar energy central water heating system
The JINYI solar energy hot water project mainly divides into three sorts:
(Ⅰ) The temperature difference follows the concentric type:

The entire system function automatically, safely, maintains conveniently. Because of the simple structure
(Ⅱ) The series-parallel type Solar water heating system
The series-parallel type for solar energy water heater .
Movement principle: Cold water enters in the solar water heater after the solenoid valve, the vacuum tube selective absorption membrane level absorption energy of light transformation heat energy causes cold water elevation of temperature. The user may through install the temperature sensor and the display unit knows in the solar water heater in the water heater the water temperature, when the water temperature achieved takes a bath when the temperature then turns on the hot water valve to use the hot water. Characteristics: small scale, simple structure , namely exposes to the sun namely uses, be suitable for the water volume is small also to the hot water request not high unit, the collective and individual.
(Ⅲ) The water-flow decides warm type solar heating system
Cold water passes through automatically sails upstream the control box to enter in the solar-powered water heater, the vacuum tube selective absorption membrane level absorption energy of light causes cold water elevation of temperature. The collection heat and the water tank are equipped with separately has the temperature sensor, when the collection heat water temperature difference achieves the setting value, namely starts the circulating pump or the solenoid valve, goes against into the collection heat in hot water the water tank heat preservation, by supplies the use.Characteristics: The water discharge is big, is suitable for the use of guesthouse or the bathing place.
The solar energy hot water project control cabinet it not only has the water level establishment, the water temperature establishment, automatically sails upstream, manually heats up, the water level water temperature demonstrated, warm controls frost proof, fixed time supplies water, temperature difference circulation and so on practical function, moreover has guards against, protection function parched and so on leakage protection, is in sole possession of the pipeline circulation function, may carry on the automatic control to the solar energy hot water project.
1. stores the water tank water temperature, the water level to demonstrate that, the collection heat water temperature demonstrated, pipeline temperature demonstration. 2. stores the water tank automatically to make up the water.3. temperature difference control collection hot circulation. The control temperature difference is 10 °C 4. fixed time warm controls the assistance to heat up. The control temperature °C establishes wilfully in 30~80.5. warm controls frost proof. The control initial temperature is 4 °C , stops the temperature is 8 °C .6. fixed time supplies water.
- Operation part: Water level establishment: Water level hypothesis scope 2 ~ 4 grades.Warm controls sails upstream: Has established the water tank control temperature after the user, when stores in the water tank the temperature ratio control hypothesis temperature is over 10 °C , the automatic start sails upstream; In the water tank temperature is lower than the hypothesis temperature or full of water then stops sailing upstream. The control temperature establishment scope 30 -80 °C , the controller starting value is 50 °C .
Fixed time sails upstream: The controller may according to the hypothesis time, the automatic start sail upstream, the water level achieved when upper limit fluid position, stops sailing upstream.
Manual sails upstream: Presses the inlet valve to start to sail upstream, automatically cuts off the water supply to the hypothesis water level, when sails upstream the condition presses once more may stop sailing upstream immediately.Fixed time heats up: The user may establish wilfully fixed time heats up the time, when to hypothesis time, if in the water tank temperature is smaller than the control temperature, the controller automatic start assistance heats up; When to hypothesis temperature, stops heating up.
Water temperature establishment: The water temperature establishment scope is 30 °C ~ 80 °C .Heats up immediately: May start the electric heating as necessary, presses once more may close the electric heating. Manual heats up: When controls the cabinet to appear the breakdown cannot automatically start the electric heating, may press manually heats up the switch, start the function for heats up. Usually this switch should be at the off-position. Water supply control: The user may establish the water supply delay time, the hypothesis scope is 00-99 minute. The controller starting value is 99 minutes. One day may establish 4 times of water supplies time.
- Completely automatic partial:
Water temperature demonstration that: The water temperature demonstration scope is 0 ~ 99 °C . Water level demonstration that: From the top downward demonstrated 1 ~4 levels of water levels, the anhydrous time 1 level of water levels indicating lamp glitters.
Guards against parched: In the anhydrous situation automatically stops heating up. Cyclic control: The collection heat temperature ratio stores when the water tank temperature is over 10 °C , starts to start the circulation; The collection heat temperature drop to is lower than stores the water tank temperature 4 °C time, stops circulating. Frost proof control: When guards against the freezing point temperature is lower than 5 °C , frost proof output start; When guards against the freezing point temperature to be higher than 8 °C , stops outputting.
Leakage protection: Has established the leakage protection circuit breaker in the power source coil in, when the phase line appears the leakage electric currently, the power source will turn off automatically .
Automatically sails upstream: Regardless of in what kind of control condition, when the water level is lower than 1/4, the controller can automatically start sails upstream.
