What Is Hot Gas Bypass?
What is the Difference Between Hot Gas and Cold gas?
What is the difference between hot gas and cold gas? They include water, electric, and hot gas. During the hot gas defrost process, high pressure hot gas from the discharge side of the compressor is introduced into the evaporator in a controlled fashion where it condenses back to its liquid state.
Water, Electric and Hot Gas
They include water, electric, and hot gas. During the hot gas defrost process, high pressure hot gas from the discharge side of the compressor is introduced into the evaporator in a controlled fashion where it condenses back to its liquid state. 2. The heat of the refrigerant is used.
The Hot Gas Bypass Valve for Evaporator Control
The hot gas valve is an energy adjustment device that will allow the high-pressure side gas to be bypassed to the low-pressure side to ensure the system can operate very well. The units that adopt the hot gas bypass valve are on a low load, it can effectively limit the evaporation pressure and prevent the system from switch on and off, ensuring the compressor runs well under the designed return gas pressure, and also effectively prevent the evaporator. The system needs to use a liquid injection valve to lead liquid refrigerant from a high-pressure liquid line to the suction line, when the liquid refrigerant evaporates, it will absorb the heat and release cool, then it can control the excessive rise of the exhaust temperature.
The expansion valve can control liquid supply for the evaporator, the oil return function is greatly improved, and the actual load is low, but the mixing chamber can be used as a direct mixing chamber. The hot gas bypass valve should be close to the compressor to avoid the hot gas from escaping. The main function of the hot gas valve is to balance the cooling capacity of the system by keeping the suction pressure low.
The first step after the installation of the hot gas bypass valve is to determine the lowest pressure under the operating conditions. If there is air flowing into the hot gas bypass valve, please listen to the sound to see if it is coming from the outlet or the valve. If you want to prevent the hot gas bypass, you can cut off the power supply to the valve in the hot gas line or adjust the lever to make sure it's in the closing condition.
False load on the HGBP detector
HGBP is used to create a false load on the evaporator in order to keep it running during low load conditions. There are a few ways to do this.
Bayt.com: A Job Site for Evaporator Operators
A hot gas valve is installed behind the expansion valve of the low side of the gas line to allow hot gas to enter the room before it enters the evaporator. The Hot Gas Bypass is a control system that is used to regulate the amount of energy used in the engine at certain times to keep it running at the most economical level. The consumption of water, fuel or electricity drops below its nominal design when air conditioning is used.
The compressor must have a capacity control system that is used by using a tool called: Hot Gas Bypass, Auto Unloader and multispeed compressors.
