Magnetic valve links to each other with the delivery port of first relay, solar water heater, floor heating pipeline and the water inlet of floor heating pipeline respectively; When magnetic valve is opened; Solar water heater and floor heating pipeline form the circulatory system; Hot water in the solar water heater is through the heating coil road, water inlet inflow place of floor heating pipeline, and the ducted cold water of floor heating flows into solar water heater through the delivery port of floor heating pipeline.Magnetic valve adopts bi-bit bi-pass closed type magnetic valve, and outage is closed, and energising is opened.Adopt top formula structure; Automatically this valve product in service life of the big prolongation of sealing compensation is producing in serial form, and volume is little, and flow is big; Seal applied widely adopts polytetrafluoroethylmaterial material (Teflon), to be suitable for the switch control voltage of different fluid: AC220VDC24V.Magnetic valve is controlled by first relay, and whether hot water inserts ground heating system in the control solar water heater, just owing to have only in the winter time between 12:00～16:00 magnetic valve to open, for saves energy, select the closed type magnetic valve.
Solar water heater links to each other with magnetic valve, is used under the control of magnetic valve, with self hot water the floor heating pipeline is provided.Solar water heater adopts the 160L cylinder body.The volume of solar water heater generally is minimum 50L per capita, and three-person household is generally selected to be advisable more than the 160L.Solar water heater has two place's purposes in native system, during summer, magnetic valve is normally closed, and hot water can heating coil road, inflow place, and the user can use through tap.In the time of in the winter time, solar water heater can arrive about 60 ℃ at 7:00～12:00 with the temperature increase in the water tank through absorbing sunshine luminous energy at fine day.The floor heating pipeline is different from radiator, because its area of dissipation is big, so 60 ℃ warm water can be used as the feedwater of vulcanizing of floor heating pipeline.Thereby the 12:00 rear electromagnetic valve opens, and makes that hot water flows into ground heating system in the solar water heater, realizes heating.After 16:00, sunshine luminous energy disappears totally, closed electromagnetic valve at this moment, and the decline of water temperature can not have influence on the heat supply of floor heating pipeline in the solar water heater.Whole system has been guaranteed the maximum use of solar energy.
The floor heating pipeline is wrapped in storage tank inside, and is attached to the inwall of storage tank, and the floor heating pipeline is the thermal component of whole air-conditioning system, generally is laid on the below, floor in house.Through regulating the ducted water temperature of floor heating, realize the adjusting of room temperature.The temperature of the ducted water of floor heating can be regulated through the temperature of the water in the storage tank.In order to realize better thermoregulation effect, the floor heating pipeline should use hot conductive performance preferably material process.Likewise, storage tank also should use hot conductive performance preferably material process, such as metal etc.
Storage tank has the heating of storing or refrigeration water source, back and to its effect that is incubated.When compact water storage tank is one cubic metre of unit volume, the saving than mass energy can have been arranged through calculating whole air-conditioning system.Within the specific limits, along with the increase of compact water storage tank, the temperature adjustment water that store night is many more, and air-conditioning system is just long more in the time that can keep next day, can practice thrift the more energy.According to present most of residenter house areas, the tentative compact water storage tank of native system is one cubic metre.Need to prove that by day, we are discharged into the water in the storage tank in the floor heating pipeline, because such method of temperature control can make temperature jump excessive, uncomfortable pleasant body is lived.We are through the mode of storage tank heating return pipe, realize the lifting to indoor temperature, and the heat in the storage tank can exchange to the ducted recirculated water of floor heating slowly like this, and it is permanent comfortable that indoor temperature can keep.
Be example with summer and winter below, further specify the concrete method for using of this practical air-conditioning system that newly provides.
