What is definition of high head pressure in a air conditioner?
High head pressure is due to the lack of heat removal during the condensing process of the refrigerant cycle. The outdoor condenser is there to transfer the heat out and condense the refirgerant into a liquid. When ever the condenser is dirty or the fan motor is not working right the result is an increase in temp. and since pressure and temp are directly related the refirgerant pressure is increased thus the term high head
Why would your air conditioner have normal head pressure and a low suction pressure?
There is no such thing as normal head pressure. It is all based on temperature and calculations. Need to know indoor air temp, outdoor air temp, wet bulb versus dry bulb. Need to know specifics. so when outside ambient temp is 90 and I'm running 255 head with a clean condenser. that isn't normail head pressure? that's pretty normal to me. working with r22 the correct answer would be. If you are sure your head pressure is where it should be, with correct freon type. low suction pressure can be caused by no blower motor, closed or blocked registers, clogged filter or evaporator, lack of airflow, undersized evaperator or oversized AC, restricted metering device(TXV, piston) blocked returns. but he is right you need a lot more info what's your superheat/subcooling? what's your delta T, is you head pressure really wre it should be? what's changed since this started happening. How low issuction pressure what's your evap saturation temp? is coil freezin up? what are your pressures exactly is condenser temp 30 degrees warmer than outside temp. with r22. do you know what you are doing????
Why do heat gives heat than cold temperature?
Beause heat is transfered by high temp to low temp.If a system heats up so that its temperature is greater than atmospheric temperature the systan has high temp than atmospheric temp as heat transfer from high temp to low temp heat radiates from the system.
What is the abbreviation for temperature?
The abbreviation for temperature is "Temp."
Why does the temperature decreases when you are outside of an air-condition room?
The temperature decreases when you are outside of an air-conditioned room because the air within the room is cooler due to the air conditioning system. When you step outside, you are exposed to the ambient temperature of the surrounding environment, which is often warmer than the conditioned air inside the room.
R134a high and low pressure readings?
For a home air conditioning unit 35 psig low and 125 - 150 psig high (depending on outdoor temp) are desirable.
What is the function of a crankcase heater in a condensing unit?
A crankcase heater is a small eclectic heater that keeps the compressor oil at a relatively warm temp. This allows the oil to circulate in the system at lower temperatures.
What is the condensing temp of boiler return water in Denver?
The condensing temperature of boiler return water in Denver typically ranges from 130°F to 140°F (54°C to 60°C), depending on the specific system and operational conditions. This temperature is influenced by factors such as the outdoor temperature, system design, and the type of fuel used. For optimal efficiency, it's important to maintain return water temperatures that allow for effective heat recovery in condensing boilers.
What is the proper refrigerant psi on 1998 Chevy Tahoe?
The term would be psig not psi. Proper psig for any a/c unit auto or not is a 40 degree evaporator and you would convert 40 to psig runningng a pressure temperature chart with engine running at 1500 rpm. I its usin R-134A the psig that equals 40 degrees Fahrenheit is 34.9 psig =40 degrees Fahrenheit at 1500 rpm. In fact , 34.9 psig is the pressure for 40 degrees no matter how many rpm. Use 40 and be safe. Don't forget ,40 psig at idle will be much lower as rpm rises and evaporator could freeze up depending on humidity and ambient temp of truck inside.
Refrigerant condensing temp. should be higher than the exiting water temperature?
As rule of the thumb, refrigerant condensing temperature should between 1-2 degreeC higher than the exiting water temperature, this temperature difference is technically called condensing temperature approach. I f the approach is below or above means, system is flooded with refrigerant or system got starve. Above method is also effective in determining if the condenser shell needs maintenance for sclale, sludge build up removal. I am refrigeration mechanic.
How safe is it to powder coat iron cast steam radiators in a home?
The label on the paint container should have whatever info you want. Figure the radiator temp will not exceed 250*F if you are using steam at 15 psig which is very high for a home system and go from there.
How do you reverse a single linked list in recursive method?
Reversing a singly-linked list is (surprisingly) simple and can be done non-recursively. The following function accepts a reference to the current head of the list and returns the new head after reversing the list. node* reverse (node* head) { if (!head) return head; node *lead, *temp; lead = head; while (lead->next) { temp = lead->next; lead->next = temp->next; temp->next = head; head = temp; } return head; } Doing the same thing recursively is a bit more tricky but it can be done as follows. node* reverse (node* head, node* prev=NULL) { node* temp; if (!head) { return head; } else if (!head->next) { head->next = prev; return head; } else { temp = head->next; head->next = prev; return reverse (temp, head); } }
Why does the temp gauge stay in the hot position?
Could be, low on coolant (a leak in the system), a stuck closed thermostat, a faulty temp gauge sending unit, a bad head gasket or cracked head (worst case scenario).
Where is the ambient temp sensor located on 2008 silverado?
Try over in the ceiling over the drivers head and it looks like a mic for the onstar system.
What is the Temp of 30 psi steam?
30 PSIG is about equal to 45 PSIA. Saturation temperature from the steam tables at 45 PSIA is about 274°F. So the steam would be 274°F, or hotter if superheated.
Find the highest and lowest element from a linked list?
To find the highest and lowest elements in a linked list, iterate the list and detect the highest and lowest elements. Details omitted ... list *head; /* pointer to first element */ list *temp; /* temp pointer list *high = null; /* pointer to high element */ list *low = null; /* pointer to low element */ for (temp=head; temp!=null; temp=temp->next) { /* iterate all elements */ if (temp == head ) { /* initial case */ high = low = temp; /* start accumulating results } else { /* otherwise */ if (higher(temp, high) high = temp; /* choose higher */ if (lower(temp, low) low = temp; /* choose lower */ } }
