You are repairing a house that has no heating or cooling ductworkWhat can be done to provide cooling and heating?
Use baseboard heaters and an air conditioner.
Is seer or hspf more important?
It depends what you use more, A/C or heat. The SEER rating pertains to cooling efficiency. The HSPF pertains to heating efficiency.
When would you use a cocurrent flow heat exchanger over a countercurrent flow?
When high temperatures may damage a heated fluid and heating requirements are low enough that can be met by the heating media temperature. Cocurrent flow heat transfer has lower heating (or cooling) capacity than counterflow and there is a theoretical cocurrent flow temperature limit achievable which is lower in heating (or higher in cooling) than the temperature achievable in counterflow.
How hvac systems work?
Heating, ventilating, air conditioning systems (HVAC) most often use a refrigerant for cooling and a furnace or heat pump for heating. Both heating and cooling are directed through the same ventilation network.
Why can't the heat generated by a combustion engine can be used as a source of energy instead of cooling engine and wasting it?
What you are after is perpetual motion, which isn't going to work. Any type of energy can be converted to heat, but heat can only partially be converted to energy. Most of the problems stem from trying to remove heat, rather than allowing it to accumulate. Heat is the graveyard of energy. ------------------------------------------------------------------- Some heat from engines can be recovered and used for space heating. The heaters in automobiles do just that. However, more often than not the build up of heat from an engine is more than is desired for auxiliary uses, and it must be discarded to keep from overheating the equipment. Some building emergency generators can use some of that heat in a heat exchanger for heating non-domestic water supplies, but the potential for leaks precludes it from use for domestic water heating.
What are the most cost efficient heating and cooling systems?
Geothermal heating and cooling systems are the most cost effective. Although they may be slightly more expensive to install, the cost of use long term is greatly decreased from traditional sources of heating and cooling.
Why is cooling a house more expensive than heating it?
It is not always the case that cooling is more expensive than heating. It depends on the type of system you have and your utility rates. It also varies based on your location. You can find out the most cost effective way to heat and/or cool your home with an advanced load calculation. Then you can decide what type of equipment to use.

Why do you use mercury in thermometers if it is not a good conductor of heat?
- mercury is a liquid metal - cooling and heating are easy reversible - cooling and heating are rapid - the relation between the temperature and the thermal expansion of mercury is linear
What ways can you use electricity?
The ways that you can use electricity include heating and cooling your home. You can use electricity for things that include cooking, heating water, keeping food cold, and for entertainment.
What are the uses for natural gas?
Natural gas can be used for heating, cooking, cooling, generation & for use in manufaturing. Applications are often similar to that of electricity. Commercial & industrial use often has more applications than residential limited primarily by the availability of appliances/equipment.
Can you use jb weld on a cracked exhaust manifold?
You can try, but it will not stay. The heating and cooling of the manifold will cause the JB weld to fall off.You can try, but it will not stay. The heating and cooling of the manifold will cause the JB weld to fall off.
