Heat Pump Dryers Save Energy and Eliminate Potential Fire Hazards
Conventional dryers make use of electric resistance or gas combustion to heat the air then blow it over the clothes. The warm, humid air is then blown outside. They don't require vents, which help save energy and prevents fire hazards due to lint accumulation in the ducts.
These machines also have lower temperatures and are gentler on clothes. They can take longer to dry than traditional machines. Learn more about these ventless laundry machines from Aztec Appliance.
Efficiency
You can save lots of money on your electricity bill by using the heat pump dryer. According to Energy Star, it uses up to 28 percent less energy than a conventional clothes dryer. That may not sound like much, but when your family is doing 20 loads of laundry each week in Massachusetts where electricity prices are among the highest in the nation, you'll save hundreds over the course of 12 years with a heat pump dryer.
The way a heat-pump dryer works is similar to the way it works dehumidifiers. The heat pump dryer starts with heated air that is then sent through coils to warm it further. In this process, the hot air draws moisture from the clothing and then into the heat exchanger, where it transforms into condensed. It then drips into a empty pan or a tube that can be connected to drain it. The cooled, moist air is then circulated back through the coils of the condenser, to be heated.
They don't require an exhaust vent, so they can be used in places that wouldn't accommodate a conventional dryer. They also are more efficient and quieter which makes them suitable for homes and other areas that have little space. They are also safer than dryers that have vents. Vents can spark fires when they aren't cleaned regularly.
However, since they operate at lower temperatures than conventional dryers, it takes longer for your laundry to dry using a heat pump dryer. It is also essential to clean the dryer on a regular basis since it functions as a dehumidifier, and produces plenty of moisture during the drying process. This is particularly important when you live in a humid environment or if your clothes are soaked with lots of moisture in the dryer. It is possible to do this by checking and cleaning the lint screens and the condenser coils. It is also recommended to clean the drain tube occasionally. Regular cleaning will keep the evaporator coil in good working order.
Condensation
The most common method of drying clothes is to use a fan to blow hot air over the clothes. This air is then vented to the outside. This approach uses a lot of energy and requires access to an outdoor space vented to allow for ducting. Heat pump dryers, also known as ventless drying equipment, recycle air. They are able to heat the air by reusing energy used to power the machine, and then condense it into water that drains out of the bottom of the drum. They are smaller than vented models and can be installed in a laundry room or attic.
Although they are widely used in Europe and Japan the heat pump dryers are new to the American market. They're now available in sizes that would fit in the majority of laundry rooms and offer significant energy savings and other climate benefits. Because they don't draw the indoor air to the outside, you don't have to clean your venting system often or deal with potential issues that can arise when you have a dirty venting system.
They are similar to the refrigeration system of a refrigerator. They have a compressor which pressurizes refrigerant into one set of coils, which releases heat. The evaporator coils absorb heat from air that flows through. The refrigerant that is heated circulates through two coils to condense the moist air, and that chilled refrigerant is then recirculated back into the original set of coils and is reheated to repeat the process.
As with other electric dryers, a heat pump dryer still needs maintenance to ensure that it is operating at its peak. Lint can build up on filters and evaporator coils. It is important to clean these frequently to prevent excessive wear. They also employ refrigerants that have high GWP or Global Warming Potential. They need to be recycled.
They take longer than vented dryers in drying a load. That's because their maximum temperature--about 120degF, is lower than electric and gas resistance dryers. Therefore, they have to tumble for an additional time before they're dry.
Lint Screens
The dryers of a heat pump come with a lint trap and venting system which need to be cleaned on a regular basis. A blocked vent can drastically lengthen drying times, and is a fire hazard. The exhaust of a vented dryer can reach temperatures high enough to ignite volatile oils and chemicals on clothes.
A heat pump's vent system requires a dehumidifier in order to remove moisture from the air prior to it exits the dryer. A dehumidifier will also help you save energy by lowering the temperature at which hot water is heated to heat the air.
visit these guys on the heat pump dryer is more fine than in conventional dryers, which is why it requires cleaning more frequently. The lint screen that is located in the door opening can also build up lint. It should be cleaned regularly.
The models with a heat pump come with a heated drum, which means the inside of the machine must be kept free of residue and lint from dryer or fabric softener sheets. The heated drum walls also require periodic cleaning and inspection, as they may need to be replaced as specified in the user's manual.
According to the U.S. Fire Administration, lint buildup inside the dryer's exhaust pipe is more than just an inconvenience. It's also a fire hazard that causes 2900 house fires per year. Clean your dryer's lint-exhaust hose once a year using wire brushes, or employ an air blower from outside to remove lint from the inside of the hose as this How-to video provides. This is safer to do from the outside, as you won't be able to see lint on your face. If you're not sure of your ability to clean the duct, get a professional to do it for you.
If you don't feel the air moving through the dryer vent, or your dryer takes longer to dry, it could be that there is a lint blockage within the duct. Choose a specific day in the year to clean the venting system - Labor Day, the beginning of spring, or the closing or beginning of daylight savings time - and adhere to it.
Installation
Drying laundry with a modern electric dryer is one of the most important features available to homeowners. But choosing the best dryer is crucial for those who want to cut down on their energy bills and have a positive impact on our environment. For many, heat pump dryers are an ideal choice. Heat pump dryers are different from vented dryers like traditional ones that use electricity or gas combustion for heating air, and then blowing hot, dried air into the drum in order to remove moisture. They reuse the air, pulling out the moist and cooling it and allows it to return to the laundry room so that it can again be used.
Since they don't require venting outside, they don't require any chimneys or ducting, and can be put in small spaces, such as laundry closets. They're ideal for tiny houses, accessory dwelling units (such a laundry room or apartment above the garage), and even additions. And because the ENERGY STAR label is a reliable mark of energy efficiency, dryers with heat pumps are typically more efficient than traditional vented models.
Heat pump dryers can be used on standard 120-volt 15 amp circuits. This is a benefit for older homes that have older wiring, and can help you save money on installation.
They have lower power than other dryers, so they take longer to complete the cycle. Since they don't move back and forth like conventional dryers do, large items like sheets and towels can become a laundry sausage that is difficult to remove. Some manufacturers try to solve this problem by reversing tumble cycles for short periods during the cycle.
In addition, heat pumps need more regular maintenance than other dryers. Lint can collect on the heat exchanger coils and evaporator coils, requiring periodic cleaning or vacuuming to ensure that they run efficiently. Heat pump dryers don't vent, and therefore they may accumulate moisture inside the dryer. This can lead to mold.
