Description

Description Air Source Heat Pump Combined With Solar Panel This invention relates to combining an air source heat pump with a solar panel. Nowadays, with new technology being invented with regards to the climate, combining an air source heat pump with a solar panel would help reduce the green house gasses and carbon dioxide emissions. Modern day's boilers being manufactured in the present are still running on natural gas, this produces co2 and depending upon the servicing and well maintenance of the appliance, it can produce carbon monoxide to leak into the property which is not safe if breathed in. if you combine an air source heat pump along with a solar panel, the heat pump would use the outside air to provide heating and cooling but also allowing the solar panel to be powered from the sunlight. This would allow the heat from solar panel to be generated to pass onto the heat pump heat exchanger allowing the water to become hot quicker and more efficiently by combining the two heat exchangers together in one unit. Thus producing zero carbon emission to the environment. The heat pump can be switched in the summer to provide cooling working alongside with the solar panel to provide hot water for the user and heating for the winter by combining both solar panel and the heat pump to provide heating and hot water. The heat exchangers are designed in such a way that one heat exchanger from the solar panel contained with glycol liquid is wrapped around the heat exchanger of the heat pump also containing glycol liquid similar to spinning both spring coils together until both coils turn into one to allow heat transfer via convection to the third heat exchanger in between the coils. Also containing glycol liquid. As shown in figure 1. Then we would drill 2 holes into the cylindrical heat exchanger for the flow and return pipes to be welded onto the cylindrical heat exchanger for the glycol liquid to be circulated around the pipe work to make the radiators hot or cold and hot water for the cylinder. This would act as the main heat exchanger for the heating or cooling and hot water circuit. As shown in figure 2. Once the heat exchangers have been manufactured, we would house that in a stainless steel sheet by bending the sheet into a cylindrical container. This would allow all the heat generated from the 3 heat exchangers of the systems to contain within the cylinder therefore less heat loss within the system. As shown in figure 3. The stainless steel heat container would then be seal from side and to side, top and bottom by a process called TIG welding. As shown in Figure 4. The glycol liquid would be filled at the heat pump, solar panel and main cylinder pipe work using a valve as a filling point. This would allow both systems to work together throughout the year during both summer and winter seasons. Figure 5, 6,9, 10 Explained If the solar panel is on the other side of the house and the heat pump the other, then we could have 2 separate junction boxes and 2 receivers to wire the 2 port valve system. There would be 2 receivers. The receiver would be powered by a 3 wired live neutral earth cable. Those 3 wires would then be connected to the junction box where each live neutral earth cable of the components such as pump and 2 port valves are to be connected. The brown wire from the motorised valves would be connected to the receiver to power the cylinder thermostat and 2 port valves. The grey wire from the heat pump hot heating, hot water, cold circuit and would be connected to the junction box. Those three grey wires would then extend from the junction box to connect to the printed circuit board at the heat pump. The solar panel motorised valves and cylinder thermostat would be wired exactly the same way with the receiver being powered by a live earth and neutral which would then serve a junction box to connect the rest of the wires from the cylinder thermostat and the two 2 port motorised valves for heating and hot water. The grey wire would also be wired at the junction box. The 2 port motorised valves brown wire would be connected from the junction box and extend the brown wire from the junction box to the receiver to power the cylinder thermostat and the two 2 port valves, The 2 receivers would have a wireless interface similar to a Bluetooth device with a simple button to activate its signal with to push and connect to the room thermostat. The room thermostat would be powered by a simple 2 AA batteries. The temperature of the cylinder thermostat would be adjusted at the thermostat attached to the hot water cylinder. For example, there is a demand for heating and hot water at the heat pump thermostat, that would then send the signal via the brown wire activating the motorised valves syncron motors telling the pump to start circulating at the heating circuit as well as sending a signal through the grey wire to activate the heat pump reversing valve to switch to hot mode and the heat pump runs. There would be 3 circuit boards need inventing, one for the heat pump for the component wiring, one for the receiver wiring, and the other for the room thermostat.
