The course of work of the present invention is specific as follows:
When the present invention used in summer, state switch is pushed " summer refrigerating state under ".Morning; Solar panel output voltage under the irradiation of the sun increases gradually; When output voltage surpasses the output voltage of three terminal regulator; First relay gets electric, and the second relay work is given in power supply after its normally opened contact closure, and the second relay work gets electric back normally-closed contact and breaks off then conducting of normally opened contact.Heat three-way magnetic valve 21, outdoor fan 32 and outdoor three-way magnetic valve 31 this moment and get electrician's work, indoor fan 42 breaks off with indoor three-way magnetic valve 41 dead electricity.Meanwhile, zeolite case 1 temperature under the irradiation of solar energy raises gradually, when the temperature of zeolite case 1 reaches 38 ℃, begins the adsorbed water that desorption goes out the zeolite molecular sieve the inside, and desorption finishes in the time of 120 ℃.High temperature desorption current flow to the bend pipe of outdoor condenser 3 via heating bend pipe, and hot water through the heat conduction, is passed to heat and supplies the user to use in the water in the boiler 2 in boiler 2.Afterwards, desorption water is in outdoor condenser 3 bend pipes after the cooling via fin heat radiation and outdoor fan 32, to flow directly in the water storage box 5 behind the straight-through indoor three-way magnetic valve 41 of room temperature.In evening, the voltage of solar panel reduces gradually, and when output voltage was lower than the output voltage of three terminal regulator, first relay electric-loss, second relay be dead electricity thereupon also, this moment the normally opened contact of second relay break off, the normally-closed contact adhesive.Heat three-way magnetic valve 21, outdoor fan 32 and outdoor three-way magnetic valve 31 dead electricity this moment and break off, indoor fan 42 gets the electrician with indoor three-way magnetic valve 41 and does.Zeolite case 1 is not having under the situation of the sun; The a large amount of adsorption moistures of zeolite in the zeolite case 1; Emit heat of adsorption towards periphery, the water vapour molecule in the water storage box 5 is flowed through behind the bend pipe of indoor condenser 4, flow in the zeolite case 1 behind straight-through indoor three-way magnetic valve 41 and the outdoor three-way magnetic valve 31.Because zeolite case 1 constantly absorbs steam, emits heat of adsorption, its entropy is converted into the refrigerating capacity of water storage box 5, makes the temperature of water storage box 5 constantly reduce, together with refrigeration case, until dropping to-2 ℃～-3 ℃.Whole system is moved under negative pressure, and the low temperature " cold air " that constantly by indoor condenser 4 steam about zero degree is had in the adsorption process blows to room temperature lowering.The negentropy that heat of adsorption gives out the space is compensated by the entropy of room temperature lowering fully.
When the present invention used in winter, state switch is pushed " heat under the state winter ".Daytime is under solar energy impinges; Output voltage increases gradually, and when output voltage surpassed the output voltage of three terminal regulator, first relay got; The second relay work is given in power supply after its normally opened contact closure, and the second relay work gets electric back normally-closed contact and breaks off then conducting of normally opened contact.Heat three-way magnetic valve 21, outdoor fan 32 and outdoor three-way magnetic valve 31 dead electricity this moment and break off, indoor fan 42 gets the electrician with indoor three-way magnetic valve 41 and does.Meanwhile, desorption goes out high-temperature water to zeolite case 1 shining upon down, behind this desorption water straight-through refrigeration three-way magnetic valve and the outdoor three-way magnetic valve 31, flow in the bend pipe of indoor condenser 4.In this process, indoor condenser 4 blows " high temperature " in the high-temperature water to indoor intensification.In evening, the voltage of solar panel reduces gradually, and when output voltage was lower than the output voltage of three terminal regulator, first relay electric-loss, second relay be dead electricity thereupon also, and this moment, normally opened contact adhesive, the normally-closed contact of second relay broke off.Heating three-way magnetic valve 21, outdoor three-way magnetic valve 31, outdoor fan 32, indoor three-way magnetic valve 41 and indoor fan 42 equal dead electricity this moment breaks off.The straight-through indoor three-way magnetic valve of water in the water storage box 5 41, outdoor three-way magnetic valve 31 and heat three-way magnetic valve 21 after flow in the zeolite case 1; Emit heat of adsorption to atmosphere in the process of a large amount of steam of zeolite case 1 absorption, and make water storage box 5 refrigeration freeze to about-3 ℃.Because this moment, indoor condenser 4 was not opened, outdoor fan 32 is not opened with indoor fan 42, thereby little for the indoor temperature influence.
The present invention is not limited only to the foregoing description; The electric weight that is produced at thermo-electric generation assembly 7 and solar panel is during greater than the required electric weight of cycle refrigeration system; The electric weight of battery stores can be made for and be the power supply use; Can connect an inverter this moment at the two ends of battery, and battery can be used by room lighting or other external equipments.
