Here’s how it works:
- Liquid refrigerant is pumped through the expansion device, functioning as an evaporator.
- Air from inside is blown across the coils and heat is absorbed by the refrigerant.
- Cool air is blown throughout the home.
- The liquid refrigerant heats up and evaporates into a gas.
- That gas passes through a compressor, which pressurizes it.
What is the purpose of a coolant pump?
Unsourced material may be challenged and removed. A coolant pump is a type of pump used to recirculate a coolant, generally a liquid, that is used to transfer heat away from an engine or other device that generates heat as a byproduct of producing energy. Common applications of coolant pumps are:
How does a heat pump cooling system work?
The hot gas is cooled in the indoor unit by passing air, heating the air and condensing the the gas to warm liquid. The warm liquid is relieved of pressure as it enters the outdoor unit, turning it to cool liquid and renewing the cycle. A heat pump is a versatile, efficient cooling and heating system.
How does the coolant in a car engine work?
On older cars the tubes run vertically, but modern, low-fronted cars have crossflow radiators with tubes that run from side to side. In an engine at its ordinary working temperature, the coolant is only just below normal boiling point. The risk of boiling is avoided by increasing the pressure in the system, which raises the boiling point.
What happens when the coolant pump is discharged from the reactor?
At the discharge of the reactor coolant pump, the reactor coolant pressure will be approximately 0,5MPa higher than the inlet pressure. After the coolant leaves the discharge side of the pump, it will enter the cold leg and continue to the reactor.
What happens when coolant pump fails?
A dead or dying water pump cannot circulate coolant through your vehicle's engine and, as such, the engine will overheat. The hotter the engine gets the greater the chance of serious damage, including a cracked engine block and damage to the cylinders, pistons, and head gasket.
What drives the coolant pump?
Standard coolant pumps are driven by a belt drive, which in turn is supplied with mechanical energy from the combustion engine. This increases fuel consumption and reduces the useable mechanical power of the combustion engine.

Is there a difference between a water pump and a coolant pump?
The water pump, often referred to as the coolant pump, circulates liquid coolant through the radiator and engine cooling system, and is powered by the engine itself. It ensures that the engine temperature is maintained at a safe level while operating.
Is the water pump connected to the coolant?
What Is a Car's Water Pump? The water pump is the heart of your car's cooling system. It pumps coolant through the engine to keep it from overheating. A water pump doesn't move water alone; it controls the flow of coolant through your engine, and the coolant is usually a blend of water and antifreeze.
Why is my coolant not circulating?
Tip: If the coolant is not circulating, then it may need a new water pump. The water pump test should only be done after you verify whether or not the thermostat is faulty.
How do you know if your water pump is not working?
With the engine off, open your hood and locate the water pump pulley. With gloves on, grab it and wiggle it back and forth. There should be no movement, if there is, this along with the noise is a good indication you may have a water pump problem.
Why is my car overheating but it has coolant in it?
However, if your car is overheating, but the coolant is full, it is probably not a leak. Instead, it may be that it's having trouble circulating correctly. This can stem from several things, including a faulty water pump, a radiator blockage, a stuck thermostat, or a plugged heater core.
How does coolant flow thru radiator?
The coolant flows through the thin tubes that make up the core of the radiator and is cooled by the air flow through the radiator. From there, it flows out of the radiator, through the lower radiator hose and back to the water pump. By this time, the coolant is cooled off and ready to collect more heat from the engine.
What forces the coolant to flow throughout the engine?
Coolant follows a circulation path that begins with the water pump. The water pump's impeller uses centrifugal force to draw coolant from the radiator and push it into the engine block. Pumps are usually fan, serpentine timing belt, or timing chain driven. Nowadays, they may even be driven electrically.
Does coolant go to heater core?
The heater core has tubes that circulate hot engine coolant through them before the coolant is returned to the radiator. Air blows over the hot coolant to warm it before it's blown through your vehicle's vents.
