Wall-Mounted Heat Pump Sharp ZHU of 18 000 BTU Montréal

New refrigerant and energy efficiency

At AirGreen, we are proud to work in tandem with SHARP to provide solutions that are both reliable as well as environmentally responsible and sustainable. Most importantly for you, an efficient heat pump is also a reliable heat pump. Due to their high levels of efficiency and reliability, SHARP systems are among the very best for extreme climates such as the ones we face in Quebec.

As a sustainable company, we emphasize sustainability and responsibility in our core values and purpose. Our new SHARP heat pumps and air conditioners align perfectly with our mission through the use of a new, more energy-efficient refrigerant. Indeed, AirGreen is proud to offer this series that protects the environment by reducing the product’s energy footprint, which will inevitably also help your home’s budget.

The new R-32 refrigerant reduces greenhouse gases and the electrical consumption of the appliance by around 10%. The usage of this refrigerant therefore improves the overall efficiency of the heat pump. This refrigerant has a much lower global warming potential than refrigerants commonly used in other heat pumps such as R-22. The ZHU series is a product that consumes less electricity and therefore contributes to the fight against climate change.

Nature Wing: Fan Blades

You will notice a theme in the SHARP products that we sell: the central importance of nature and the environment. This inspiration is manifested again in the ZHU series’ fan blades installed in the indoor and outdoor units.

Indeed, the indoor heads are equipped with ventilation blades in the shape of dragonfly wings. This design improves airflow by approximately 30% according to experiments conducted by SHARP which compare the amount of energy used to push airflow between a regular blade design and models with the blades of dragonfly.

Next, the exterior compressor of the ZHU series features fan blades that combine the wing shapes of two animals: the golden eagle and the albatross. The thinness of the golden eagle's wing is ideal for controlling airflow while the long wings of the albatross improve the airflow’s overall power. According to tests conducted by SHARP that compare the amount of electricity needed to push a certain airflow, models with a bird's wing design improve airflow by approximately 20%.

Plasmacluster: superior air purification

SHARP products are the only ones that work to imitate and reproduce natural air purification. This technology is specific to SHARP products and allows these heat pumps and air conditioners to stand out from the competition. You will not find any mini-split or central heat pump that neutralizes airborne bacteria and viruses, in addition to eliminating mold and other contaminants in the indoor air of your home. Plasmacluster technology purifies the air and protects your health. It offers many advantages:

• Eliminates airborne viruses
• Removes mold and airborne microbes
• Fights odors and tobacco residue
• Fights airborne allergens
• Breaks down and removes sticky odors in your home

How does it work?

The Plasmacluster mechanism provides superior air purification and elimination of mold, viruses, allergens, and odors. This neutralization is done in three main steps:

1. Diffusion of ions
   • An ion is a molecule carrying an electrical charge. There are two categories: cations (with a positive charge) and anions (with a negative charge).
   • Plasmacluster cations and anions are identical to those found in nature. These ions are surrounded by water molecules, which gives them a very long life. The discharges of the Plasmacluster make it possible to diffuse the necessary ions.
   • You should know that positive ions (H+) and negative ions (02-) are constantly present in the ambient air, although in another form.
2. Plasmacluster ions attack allergens, mold, and airborne molecules.
   • The diffused ions create highly oxidized hydroxyl radicals (HO) which can attack allergens, viruses, and mold. Ions remove hydrogen from surface proteins. In this way, the Plasmacluster ions attack and destroy the contaminants.
3. Transformation of ions into water and humidity
   • Hydroxyl radicals join with hydrogen (H) to return to the surrounding air as newly created water (H20).

Sharp is a world leader in air purification products and technology. Their products equipped with Plasmacluster technology reached the threshold of 100 million units sold in 2022.

COANDA Airflow Control

While it is certainly true that SHARP heat pumps stand apart thanks to their air purification, it is also true and even more notable that their airflow redirection and control mechanisms are a feature also unique to SHARP. This is the Coanda airflow. Unlike the Plasmacluster, the Coanda effect was not invented by SHARP, but rather it is a phenomenon observed in nature. SHARP mini splits simply use natural properties to ensure temperature uniformity in your home. The Coanda technology on the ZHU series ensures that you won’t have to worry about uncomfortable airflows in front of the indoor unit.

At AirGreen, we understand that many homes in Montreal and Quebec will have a wall-mounted mini split with an indoor head located away from certain rooms. If the installed product is not well chosen, the home may end up with a great lack of uniformity in heat and cool air throughout different areas. Since we don't want to be cold in one room and hot in another, the ZHU series products once more work in tandem with Mother Nature through the Coanda effect. In nature, we can observe and measure the tendency of gases and liquids to be attracted by certain convex surfaces over which they flow. The flow follows an initial surface and then undergoes a deflection which will detach the fluid on a new trajectory. SHARP heat pumps and air conditioners take advantage of this phenomenon by directing the air along the appropriate walls and ceilings, depending on whether you want to heat or cool. Thus, by reaching strategic surfaces first, ZHU systems allow temperature harmonization in the targeted rooms.

The Coanda airflow control mechanism also allows Plasmacluster ions to flow into deeper corners of your home. It is an excellent technology that avoids direct contact between the air in the system and the inhabitants of the dwelling. If you are looking for ambient comfort without a room or space becoming too hot or too cold, Coanda airflow offers you the best solution.

It is always important to install a heat pump that is powerful enough to cover the space, but with the combination of Plasmacluster and Coanda technologies, you will have the peace of mind of having a more uniform temperature and air purification everywhere.

The long diffuser flap on the interior units of the ZHU series is an addition that contributes to the unparalleled airflow control of SHARP products. The diffuser shutter performs several functions at once. It maximizes air intake to the interior head while minimizing airflow losses. Furthermore, the airflow is directed so as not to blow on the user. You can therefore install the ZHU series without worrying about a draft felt by the occupants of the space directly in front of the interior head.

The long diffuser flap allows a controlled airflow at distances of up to 15 meters. Since it directs cold air upward and warm air downward, the airflow produced by the mini split will not disturb the occupants of the room. Fluid mechanics inspires this unique shutter which opens differently according to the needs of the occupants.

Another nice addition is the 4-way sweeping that establishes horizontal, vertical, right-side, and left-side airflow to ensure all spaces are evenly cooled and heated.

SHARP Connectivity

There is no two ways about it: the brand-new ZHU mini split series is SHARP's best line. It is an industry benchmark for several reasons. Even before considering their superior energy performance, the ZHU series are equipped with new motion-sensor technology. Your ZHU heat pump sends you notifications when someone arrives at home and also lets you know when there is no movement in the room for an extended period of time. These options make it possible to optimize the use of your appliance by minimizing energy waste.     

Real-time measurements

• Through your smartphone app connected to the heat pump, you can check and adjust certain measures in real time. In addition to showing the user if someone is present in the room, the application displays the temperature and humidity in real time.

Energy Efficiency

• The app keeps a history of system usage in order to allow you to see the electrical consumption of the heat pump.
• Monthly and daily power consumption graphs are added to detailed graphs that allow you to check the power consumption over a single day.
• SHARP's ability to monitor energy expenditure can help homeowners become aware of their habits in order to optimize them and avoid waste.

Multi-Zone Option

• This new series of SHARP heat pumps also allows you to simultaneously control different indoor units of multizone installations.
• For example, you can turn off all indoor units simultaneously even if you are away from home.

Remote locking

• If you activate the GPS function of your cell phone, you can also benefit from GPS interlocking of your heat pump or air conditioner.
• If you leave your home with the ZHU mini split turned on while you are away, the app will notify you that the system is on to give you a reminder to turn it off or adjust it if you wish.
• When the GPS notices you are returning home, the app will inform you of the ambient temperature to allow you to turn on the heat pump and choose a new target temperature if you wish.

SHARP and “Energy Star Cold Climate®”

This new line of SHARP products is certified by Energy Star ® to work in extreme cold, the cold that we will invariably encounter in Montreal and Quebec.

ZHU heat pumps are designed to perform efficiently in extremely cold temperatures and are equipped with industry leading heating technology.

Compared to most heat pumps on the market, the ZHU series offers an outdoor compressor that is more efficient in its electrical consumption. This allows ZHU heat pumps to remain powered on until very cold in the winter, as they retain their heating capacity in more extreme temperatures.

While most heat pumps must be turned off at temperatures of around -15°C, ZHU heat pumps, certified "extreme cold", can heat your home to outdoor temperatures of -27°C.

SHARP’s Unique Function Modes

Multi Space Function

In addition to the use of the Coanda effect, SHARP mini splits have the Multi Space button which allows heat pumps and air conditioners to distribute air in several rooms in a uniform and balanced way. The multi-room button on your ZHU mini split balances and harmonizes the temperature of several rooms. This airflow control is achieved with a rotating flap that can rotate up to 180 degrees. To heat, the shutter makes sure to send more hot air downwards. To cool, the flap directs the airflow upwards. Moreover, you can also change the angle of the flap according to your preference in order to achieve your ideal comfort.

Knowing that Quebecers seek evenly distributed comfort throughout their homes, this function makes it possible to heat or cool several rooms in a uniform manner. This effect is achieved with a continuous airflow that allows the ambient air to reach the desired temperature gently and everywhere in your home. Since heat pumps and air conditioners must often service multiple floors or just a very large space, the indoor unit doesn't stop circulating air when the immediate space reaches the desired temperature. With the ZHU, you can rest assured of the harmony of temperature in the different rooms and floors of your home.

“Spot Air”

If you are instead looking to prioritize immediate comfort in a specific part of a room or space, you can do so using the “Spot Air” button on your SHARP heat pump or air conditioner. SHARP mini splits separate the space in front of the interior head into six zones. Users can choose a target area with the remote control. Only the selected area is quickly cooled or heated, saving you energy consumption when you don't wish to cool or heat your entire home.

Auto-changeover

During the very worst and intense cold or hot weathers, the system is placed in heating or cooling mode, like any other heat pump. However, there are seasons with considerable temperature variations where you will sometimes need to heat and sometimes to cool.

To simplify operation and improve your comfort, SHARP systems have an “Auto Changeover” function that allows you to choose a desired room temperature without having to change between heating and cooling. The heat pump will switch from one mode to another depending on the outdoor and indoor temperature variations that occur.

Note that this feature is not available for multi-zone systems.

Auto Restart

When you install and use a heat pump or air conditioner, power outages are almost certain to occur while your system is running. The SHARP heat pump is equipped with an automatic restart function that will allow the system to properly restart under the settings it before the power outage without the user having to do anything.

Quick Defrost

Under the extreme winter seasons in Quebec, the outdoor units of heat pumps must sometimes complete a defrosting task. When the heat pump performs this function, the heating is suspended inside. With this technology, SHARP systems allow you to shorten defrosting time by 60%, resulting in better room temperature conservation and maintaining your comfort.

Hot Gas Pipe (patented)

Sharp has developed a new way of heating that optimizes heat pump operation using a hose that prevents the outdoor compressor drain holes from being blocked by ice and other debris when the machine is defrosting.

Hot Gas Pipe technology succeeds in protecting the outdoor compressor from extreme weather conditions without having to generate additional heating. Indeed, all heat pumps will sometimes produce unused heat for indoor heating. What sets SHARP's Hot Gas Pipe technology apart is that it uses unused heat to protect the compressor from ice and debris clogs. This technology achieves an HSPF level of 13.5.

Anticorrosive coating

SHARP compressors are fitted with a special anti-corrosive product which is applied to different parts of the unit. This coating improves the long-term durability and reliability of the unit, allowing us to offer you an excellent warranty on all SHARP products.

Inverter technology

In addition to offering excellent performance, SHARP heat pumps are designed to save energy. It is therefore essential that all SHARP heat pumps sold by AirGreen have SHARP Inverter technology. An inverter circuit in the compressor can control and maintain room temperature. It allows inverter heat pumps to stay on by varying the airflow. Heat pumps without an inverter must constantly shut down and restart, which greatly increases energy consumption.
