Question

Manifold gauge set hoses should have self-sealing connectors or hand valves to: _________.

a) minimize the chance of an explosion during use
b) prevent venting during recycling
c) prevent a vapor lock during rapid liquid transfer
d) minimize the release of refrigerant when the hoses are connected and disconnected

Answer 1

Manifold gauge set hoses should have self-sealing connectors or hand valves to minimize the release of refrigerant when the hoses are connected and disconnected, preventing environmental pollution.

Step-by-step explanation:

The student asked why manifold gauge set hoses should have self-sealing connectors or hand valves. The correct answer is: to minimize the release of refrigerant when the hoses are connected and disconnected. When working with refrigerants, it is crucial to prevent their release into the atmosphere due to environmental concerns and regulations. Self-sealing connectors and hand valves provide a mechanism to seal the hose immediately upon disconnection, effectively reducing the amount of refrigerant that may escape through the hole. It is important to note that refrigerants are also under high pressure, and sudden release can present hazards. However, the primary purpose of these devices is to prevent refrigerant venting, which could contribute to environmental pollution and depletion of the ozone layer.
