Thinking of buying a new furnace or air conditioner this season? Heating and cooling systems aren’t something a homeowner purchases regularly. If well cared for, the average furnace can last 20 years or longer, and an air conditioner can provide up to 15 working years.
Because you don’t purchase or work with either unit regularly, it may be difficult when it comes time to comparison shop for new technology. What is an HVAC system? What about efficiency?
What do you really need to know? This guide will help you with some of the key terms that will make shopping for a new HVAC system a little easier.
What is an HVAC system?
Heating comes from a furnace. Cooling comes from an air conditioner. So what is an HVAC system? It stands for: heating, ventilation, and air conditioning. While both your furnace and air conditioning unit are important for heating and cooling, neither would be possible without a ventilation system. It’s what drives the heated or cooled air throughout your home, keeping you comfortable even in extreme weather. Ventilation systems need to be cared for just like your heating and cooling systems, and may need repair or replacement along the way.
What heating and cooling terms should you know?
Air conditioner – an air conditioner is a cooling system that pulls heat from inside your home and pulls it outdoors to ensure your indoor comfort levels are maintained.
Air ducts – pipes or tubing that distribute conditioned air to each room inside your home. These pipes or tubing exist behind walls, in the attic, or in the ceiling.
Condenser coil – a condenser coil is a part of the air conditioner that takes in air from the outside while refrigerant moves throughout the coil.
Dampers – manual or motorized dangers exist in your floors and ceilings and act as a mechanism to control airflow into each room.
Ductwork – the overall ventilation system that allows air to flow from the furnace and air conditioner to every room in your home.
Efficiency – this describes how well a furnace or air conditioner heats or cools your home. How much energy is wasted during the production of the heated or cooled air supply. You’ll find several terms to help you determine efficiency:
AFUE – Annual Fuel Utilization Efficiency – this ratio measures a furnace’s capability of transforming heat into energy. Higher ratios mean better performance.
EER – Energy Efficiency Ratio – a measurement used to calculate air conditioner efficiency.
SEER – Seasonal Energy Efficiency Ratio – measures heating and cooling efficiency levels.
Evaporator coil – refrigerant cycles through the coil to cool down the surrounding air. This chilled air is fed through the ductwork and back out into your home.
Furnace – a furnace is a heating system that produces warmed air and distributes it throughout your home.
Indoor air quality – indoor air quality (IAQ) is used to assess the amount of pollution that resides in your home. This can track everything from dust mites and pollen to mold and mildew.
Thermostat – a unit that is responsible for controlling and setting your preferred temperature inside the home.
Je, unafikiria kununua tanuru mpya au kiyoyozi cha hewa msimu huu? Mifumo ya joto na baridi si kitu mmiliki wa nyumba hununua mara kwa mara. Ikiwa umechukuliwa vizuri, tanuru ya wastani inaweza kudumu miaka 20 au zaidi, na kiyoyozi cha hewa kinaweza kutoa hadi miaka 15 ya kazi. Kwa sababu wewe si kununua au kazi na yoyote ya kitengo mara kwa mara, inaweza kuwa vigumu wakati inakuja wakati wa kulinganisha duka kwa ajili ya teknolojia mpya. Mfumo wa HVAC ni nini? Namna gani kuhusu ufanisi? Ni nini hasa unachohitaji kujua? Mwongozo huu utakusaidia na baadhi ya maneno muhimu ambayo yatakufanya ununuzi wa mfumo mpya wa HVAC kuwa rahisi zaidi. Mfumo wa HVAC ni nini? Joto hutoka kwenye tanuru. Baridi hutoka kwenye kiyoyozi. Nini mfumo wa HVAC? Inamaanisha: joto, uingizaji hewa, na hali ya hewa. Wakati wote tanuru na kifaa cha hali ya hewa ni muhimu kwa ajili ya joto na baridi, wala itakuwa inawezekana bila mfumo wa uingizaji hewa. Ni nini inaendesha hewa joto au baridi katika nyumba yako yote, kuweka wewe starehe hata katika hali ya hewa kali. Vifaa vya uingizaji hewa vinahitaji kutunzwa kama vile mifumo yako ya joto na baridi, na inaweza kuhitaji kurekebishwa au kubadilishwa njiani. Ni maneno gani ya kupasha joto na kupoza ambayo unapaswa kujua? Kiyoyozi ni mfumo wa baridi ambayo huchukua joto kutoka ndani ya nyumba yako na kuifanya nje ili kuhakikisha viwango vyako vya starehe vya ndani vinadumishwa. Vituo vya hewa <unk> mabomba au mabomba ambayo kusambaza hewa conditioned kwa kila chumba ndani ya nyumba yako. Mabomba hayo yapo nyuma ya kuta, kwenye ghorofa ya juu, au kwenye dari. Condenser coil <unk> condenser coil ni sehemu ya kiyoyozi cha hewa ambayo inachukua hewa kutoka nje wakati baridi inahama katika coil nzima. Dampers - hatari za mkono au motorized zipo katika sakafu na dari yako na kutenda kama utaratibu wa kudhibiti mtiririko wa hewa katika kila chumba. Ductwork <unk> mfumo wa jumla wa uingizaji hewa ambao huruhusu hewa kutiririka kutoka tanuru na kiyoyozi cha hewa hadi kila chumba katika nyumba yako. Ufanisi <unk> hii inaelezea jinsi vizuri tanuru au kiyoyozi cha hewa kinavyofanya nyumba yako iwe na joto au baridi. Jinsi nishati ni kupoteza wakati wa uzalishaji wa joto au baridi hewa ya ugavi. Katika kesi hii, kuna njia kadhaa za kuamua ufanisi wa mafuta: AFU, ambayo ni kiwango cha kila mwaka cha matumizi ya mafuta, ni kipimo cha uwezo wa tanuru ya kugeuza joto kuwa nishati. Uwiano wa juu unamaanisha utendaji bora. EER (Energy Efficiency Ratio) ni kipimo kinachotumiwa kuhesabu ufanisi wa vifaa vya hewa. SEER (Saison Energy Efficiency Ratio) ni kiwango cha joto na baridi. evaporator coil  baridi mzunguko kupitia coil baridi chini ya hewa ya karibu. Hewa hii baridi huingizwa kupitia mifereji ya hewa na kurudi nyumbani kwako. Chungu <unk> chungu ni mfumo wa joto ambao hutokeza hewa yenye joto na kuigawanya katika nyumba yako yote. Ubora wa hewa ya ndani (IAQ) ni kipimo cha kiwango cha uchafuzi wa hewa katika nyumba. Hii inaweza kufuatilia kila kitu kutoka kwa chavua na chavua hadi kuvu na kuvu. Thermostat <unk> kitengo ambacho ni wajibu wa kudhibiti na kuweka joto yako preferred ndani ya nyumba.
