Why isn't there anything about Alice h Parker- the inventor of the heating furnace written about in the history books or internet or anywhere?

User Avatar

Asked by Wiki User

Alice H. Parker was indeed an important inventor who patented a gas-powered central heating furnace in 1919. The lack of widespread recognition for her may be due to historical biases that have often marginalized or overlooked the contributions of women and minority inventors. Efforts to highlight her achievements and those of other underrepresented inventors are ongoing.

Is pine wood good for making paper?

User Avatar

Asked by Wiki User

No, pine wood is not commonly used for making paper as it contains high levels of resin and lignin, which can affect the quality of the paper. Softwood trees like pine are typically used for making products like lumber, not for paper production. Hardwood trees like birch and oak are more commonly used for making paper due to their fiber content.

What is the proper ratio between outside unit tonnage and the number of vents the unit can handle?

User Avatar

Asked by Wiki User

There isn't a direct correlation between the tonnage of the outside unit and the number of vents it can handle. The number of vents a system can handle is more dependent on the size of the ductwork and the layout of the home. It's best to consult with a professional HVAC technician to determine the appropriate size unit for your specific needs.

Proper blowdown procedures are necessary to maintain the solids content of the boiler water within specific limits and to quickly eliminate contaminants if the water becomes contaminated.

How do you install a furnace in a house with a crawl space?

User Avatar

Asked by Wiki User

To install a furnace in a house with a crawl space, follow these steps:

Assess the Crawl Space: Before installing the furnace, inspect the crawl space for any signs of moisture or damage. Ensure proper ventilation by checking and, if necessary, installing crawl space vents to promote airflow and prevent moisture buildup.

Prepare the Area: Clear the crawl space of any debris or obstacles to create a suitable workspace for installation. Ensure there is adequate space for the furnace unit and access for maintenance.

Install Ductwork: If the house doesn't already have ductwork in the crawl space, install it to connect the furnace to the rest of the HVAC system. Seal all duct joints properly to prevent air leaks.

Position the Furnace: Choose a suitable location for the furnace within the crawl space, considering factors such as accessibility, clearance requirements, and proximity to existing ductwork.

Secure the Furnace: Once the furnace is in position, securely mount it according to the manufacturer's instructions. Ensure it is level and stable to prevent any movement or vibration during operation.

Connect Utilities: Connect the furnace to the power supply and fuel source, whether it's gas, oil, or electricity. Follow local building codes and safety guidelines when making these connections.

Test and Commission: After installation, test the furnace to ensure it functions correctly. Check for any leaks, unusual noises, or malfunctions. Once everything is in working order, commission the furnace for regular use.

By following these steps and ensuring proper ventilation with crawl space vents, you can successfully install a furnace in a house with a crawl space while maintaining a safe and efficient HVAC system.

What kind of head pressure would you experience if the condenser fan motor became inoperative?

User Avatar

Asked by Wiki User

The compressor would continue to operate until the high pressure safety switch shut it down, if the switch failed the pressure relief device would blow and you would lose all of the refrigerant. As far as how high would the pressure get, the settings on the two devices depend on what type of refrigerant is used and you do not mention that.

Do you check the AC with the compressor running or not running?

User Avatar

Asked by Wiki User

Checking the air conditioning (AC) compressor is an important step in troubleshooting any issues with your car's air conditioning system. Here are some steps you can take to check the AC compressor:

Visual Inspection:

Start by visually inspecting the AC compressor. Look for any signs of damage, such as oil leaks, loose or damaged belts, or physical damage to the compressor itself.

Belt Tension:

Check the tension of the AC compressor belt. A loose or damaged belt can affect the compressor's performance. Ensure that the belt has the right amount of tension and is not cracked or frayed. learn more

When you burn wood in your fireplace why does the smoke come in the house?

User Avatar

Asked by Wiki User

When you burn wood in your fireplace, smoke might enter your house due to several reasons:

The damper isn’t open: The damper controls the flow of air and smoke through the chimney. If it’s closed, smoke can’t escape and will come back into the house.

Burning the wrong type of wood: Some types of wood produce more smoke than others. Also, wet or unseasoned wood can cause excessive smoke.

The fireplace has not been used in a while: If a fireplace hasn’t been used for a long time, there could be blockages in the chimney that prevent smoke from escaping.

Fire is too big: A fire that’s too large can produce more smoke than the chimney can handle, causing some of it to spill back into the room.

Flue blockage: Birds’ nests, leaves, or other debris can block the flue, preventing smoke from exiting.

Cracked chimney or gaps in your chimney flue: These can allow smoke to leak into your home.

Backdraft problem due to multiple flues: If you have multiple fireplaces and they share a chimney, using one fireplace could cause a backdraft in another, bringing smoke into the house.

Your house is too airtight: Modern homes are often very well insulated and airtight, which can prevent the necessary airflow for the smoke to draw up the chimney.

It’s important to identify and address these issues to ensure the smoke properly vents outside and doesn’t enter your living space. If you’re unsure, it’s best to consult with a professional.

How do you get air out of auto air conditioning system?

User Avatar

Asked by Wiki User

Removing air from an automotive air conditioning system is known as "bleeding" or "purging" the system. Here's a general guide on how to do this:

  1. Identify Low Points:

Locate the low points in the A/C system, such as the low-pressure service port and any low spots in the refrigerant lines.

  1. Turn Off the Engine:

Ensure the vehicle's engine is turned off before starting the air bleeding process.

  1. Connect Service Gauges:

Connect A/C service gauges to the high and low-pressure service ports. The low-pressure side is typically used for this procedure.

  1. Open Valves:

Open the high and low-side service valves on the A/C service gauges. This allows refrigerant to flow through the system.

  1. Evacuate Air:

Evacuate air from the system by allowing refrigerant to flow until a steady stream without air bubbles is observed. This is usually done on the low-pressure side.

  1. Check for Leaks:

While bleeding the air, also check for any signs of refrigerant leaks. Leaks can introduce air into the system.

  1. Close Valves:

Once the air is purged, close the high and low-side service valves on the A/C service gauges.

  1. Recharge Refrigerant:

If needed, recharge the refrigerant in the system to the manufacturer's specifications.

  1. Restart the System:

Start the vehicle's engine and turn on the A/C system. Check for proper cooling performance.

Do they have hose less portable air conditioners?

User Avatar

Asked by Wiki User

Yes, they do have hoseless portable air conditioners. Traditional portable air conditioners typically come with an exhaust hose that needs to be vented outside to expel hot air. However, advancements in technology have led to the development of hoseless or "ventless" portable air conditioners. These units use innovative cooling technologies that eliminate the need for an exhaust hose. Instead of venting hot air outside, they often use alternative methods such as evaporative cooling or self-contained cooling systems. Keep in mind that while hoseless portable air conditioners offer more flexibility in terms of placement, they may have limitations in cooling capacity compared to traditional units with exhaust hoses.
