As Gary mentioned in a recent , reversing valves are used in heat pumps to direct the flow of refrigerant, depending on the demand for heating or cooling. Also mentioned was the fact that reversing valves have a default position when they are not energized.

Fig. 2-4-8. Reversing valve is not installed with a safety baffle (B). Remedy In order to prevent a driller from mistakenly operating the blind-ram BOP on the driller's console, the safety baffle should be installed in the reversing valve of the blind-ram BOP in the driller's console (Figs. 2-4-9 to 2-4-12 ). Fig. 2-4-9.
How a Heat Pump Reversing Valve Works HVAC School
A heat pump reversing valve reverses the process by cycling the refrigerant in the opposite way. This makes the condenser act as the evaporator & vice versa. You can see the heating cycles in the images below. Even though it can be cold outside in winter, the refrigerant can still absorb the heat outside.

Paul Evans. -. May 28, 2019. 3. Reversing valves for heat pumps. In this video we're going to be looking at the four port reversing valve, which is used in heat pumps. This is a critical component in the heat pump system, and this is what allows the refrigerant to reverse its flow to provide both heating and cooling modes.

Thermo Fluid Dynamic Design of a 4Way Reversing Valve
Four-way reversing valves are used to completely reverse the cycle of one-to-one heat pump systems. Such valves may be used to facilitate using the system for both heating and cooling, or to provide an effective and energetically optimized defrosting method. Construction
How a Heat Pump Reversing Valve Works HVAC School
A heat pump reversing valve simply reverses the process by cycling the refrigerant the opposite way. It makes the condenser function as the evaporator and vice versa. You can see the heating cycle in the image below. Even though it may feel cold outside in the winter, the refrigerant can still absorb outdoor heat.

In a typical 4-way reversing valve diagram, there are four ports labeled A, B, C, and D. The valve has two positions: the cooling mode and the heating mode. In the cooling mode, refrigerant flows in a specific pattern, while in the heating mode, the flow pattern is reversed.

Figure 2 shows a schematic diagram of such a system. Manually operated reverse heat pump system . With valves 1 and 4 open, 2 and 3 shut, coil F is the condenser and coil E is the evaporator.. of the reversing valve causes the valve to shift, and the pressure differential across the poppets holds the valve in the designated position.

A heat pump can switch from air condition mode to heat mode by reversing the refrigeration cycle, making the outside coil function as the evaporator and the indoor coil as the condenser. The refrigerant flows through a closed system of refrigeration lines between the outdoor and the indoor unit. Although outdoor temperatures are cold, enough.
Reversing Valve The Engineering Mindset
The reversing valve on a heat pump can alter the direction of refrigerant flow by means of an electrical magnet. This electro-mechanical device is a valve that is energized when electrocuted. When energized the valve opens, letting the refrigerant pass through. This would lead to the cooling mode of the heat pump.
M0079102 Reversing Valve Air Conditioning Parts/Reversing Valves
The reversing valve is a regulator that changes the direction of the refrigerant inside the heat pump. It reverses the refrigerant flow to turn the refrigeration cycle from heating to cooling or the other way around. This aids a heat pump to deliver both heating and cooling capacity, with the same equipment and just a slight change on the.
