Zhibin Yu was able to get some serious work done during the Covid-19 lockdown. He spent the time refining an innovative heat pump design that works better in colder climates.
What is a heatpump?
A heat pump is an electric HVAC system that offers cooling and heating. It utilizes the same system similar to the one in your air conditioner or refrigerator in that it evaporates refrigerant liquid, which absorbs heat from the surroundings including the air surrounding it. This heat is then transferred to the inside through a series of metal coils and a fan. Heat pumps generate heat with much less energy than electric radiators or furnaces because they make use of thermal energy extracted from the ground or air instead of generating it via combustion or electrical resistance.
A heat pump functions as an air conditioner in cooling mode, taking in heat from the outside air even when it's cold and transferring it to. It can also function as a heater during winter months when a reversing switch is switched off, converting the refrigerant back to liquid and evaporating. The heat is then brought into the indoors via a fan and copper tubes inside the indoor unit.
Heat pumps are more energy-efficient than furnaces and boilers since they generate three times as much heat. They can be used for heating your entire house or one specific area, such as garages or attics.
Heat pumps are becoming more efficient because of a variety of advancements. Variable speed compressors are among the most efficient and quieter options. Scroll compressors are also more efficient and quieter than traditional compressors. Other efficiency-boosting features include a desuperheater that heats water by recycling waste refrigerant and zones control systems that offer heating in individual rooms of the house.
The fact that heat pumps can be powered by renewable energy sources is their most important innovation. This reduces the environmental impact of the pumps, since they do not use fossil fuels to power them. They are increasingly making use of low-global warming potential (GWP) refrigerants which are more beneficial to the environment than R-410A and other hydrocarbons.
How does a heat pump function?
A heat pump extracts heat1 from the ground, air geothermal energy, other sources and transfers it to your home, providing both cooling and heating. It consumes less energy than conventional gas or electric systems, which makes it a green option. It also requires less maintenance than traditional systems.
The technology behind the Heat Pump is comparable to the air conditioner. The system is comprised of two main parts including an outdoor unit which looks like the outside unit of a split system air conditioning system, and an indoor unit that has the coil that could be used as an evaporator good or condenser. The system contains a fan which is able to blow air across the coil in order to facilitate heat transfer. The refrigerant inside the coil is liquid at temperatures of room temperature, but once it becomes hot inside the house, it turns into a gas. A reversing valve near the compressor can change the direction of the refrigerant's flow to switch between cooling and heating modes.
Because heat naturally moves to regions that have lower temperatures and less pressure, the vapor refrigerant in the coil absorbs the warmth from the air inside your home. Then, it is moved to the outside unit where the compressor increases the pressure and temperature. This causes the boiling point of the liquid to drop, and it returns to an evaporation state.
When the liquid refrigerant leaves the compressor, it goes through an additional coil in the outdoor unit. This coil is referred to as condenser when it's in cooling mode and an evaporator when the heat pump is in heating mode. The outdoor coil pulls heat out of the air by using fins made of aluminum which help transfer the heat to the evaporator.
The fan on the evaporator of the indoor heat pump blows air over the aluminum or copper coils. The coils are shaped with grooved surfaces inside to increase surface area, and help in heat transfer. The fan keeps the air moving at a steady speed to minimize drafts and reduce noise. Some models have a desuperheater which recovers the wasted heat pump tumble dryer uk from the evaporator during cooling mode and then uses it to efficiently heat water in your home.
What are the benefits of the use of a heat pump?
In terms of saving energy and minimizing your environmental footprint, there's no HVAC system that is more eco-friendly than a heat pump. This climate-friendly technology is gaining traction as local and state governments continue to offer incentives and rebates for homeowners who make the switch. The Department of Energy touts their advantages over traditional heating methods.
In contrast to gas furnaces, heat pumps use metal coils and fans to move thermal energy from the air. They do not burn fuel like a combustion-based heater and therefore don't generate any emissions or other harmful pollutants. Heat pumps do not require a chimney for exhaust fumes to be emitted out of the house. They're also incredibly quiet. They operate at a fraction the noise levels of gas furnaces.
A new study conducted by UC Davis has found that a heat pump powered by clean electricity (generated through solar, wind and other renewable sources) can cut down on household carbon dioxide emissions by up to 75 percent. However, the research only looked at houses with superior insulation and a modern heat pump, not all homes.
It's a good idea to know that heat pumps can be retrofitted to most existing homes. If you're interested in changing your heating system, we recommend that you talk to your local public power or cooperative district. They can provide information on contractors as well as financing and other aspects of this exciting new technology.
The environment you live in will determine which model is best for your home. You should look for an ENERGY label or performance chart that has a SEER and HSPF ratings. In warmer climates, it is recommended to concentrate on SEER, whereas in colder climates you should take a look at HSPF.
Heating systems aren't just green, but they also have numerous other advantages. They require less maintenance because they don't use fuel. Furthermore, there's no danger of carbon monoxide leaks, fires or explosion. The heat pump can also improve indoor air quality by increasing the humidity in winter and reducing it in summer.
Lastly they don't produce any combustion byproducts, so they don't add any combustible gases into the atmosphere. This makes them a safer choice for many homes with vulnerable residents.
What are the drawbacks of the heat pump?
Like any piece of contemporary technology, heat pumps have their advantages and drawbacks. The most important are the efficiency of energy and the environmental benefits. They unlike furnaces that use fossil fuels to produce heat, make use of renewable energy sources to transfer thermal energy out of the air or the ground and into your home. They are also more efficient than traditional heating systems and can save money on your electric bills.
They are typically more expensive to purchase than furnaces however they pay for themselves in the long run with lower operating costs. They can be noisy, however new designs minimize this problem. They are most efficient in homes that are well insulated and hermetic. They are best suited to conditions with moderate temperatures.
In summer, they function as an air conditioning. Utilizing a small amount of drive energy they draw heat from the air inside your home and exhaust it out. In winter, they operate in reverse, absorbing thermal energy from the outside air and transferring it inside.
This is made possible by a reversing valve that allows the refrigerant inside the system to move in both directions. The energy they carry can come from a variety of sources, including geothermal energy stored in the earth, ambient air temperatures or waste heat generated by industrial processes.
Since they use significant amounts of electricity (or none in the case of wall heaters), heat pumps are typically subject to 'time of use' pricing. This can raise their prices and they are not as efficient as furnaces in colder climates.
Lastly, the refrigerants that are used in heat pump systems can be released into the air and contribute to pollution. Although manufacturers are working on safer alternatives, they still pose the risk of leaking and should be used only when it is it is necessary. They are generally regarded as an eco-friendly alternative to traditional heating methods. If properly installed they can also help reduce your carbon footprint. They are a great option to live a "green" living without having to invest in a large HVAC system.
