Most vapor-compression heat pumps use a refrigerant, but “Freon” is a trademark commonly used informally for several different refrigerants. The actual refrigerant is the exact type printed on the equipment label and specified by the manufacturer. Older and newer systems can use different fluids with different pressures, lubricants, safety classifications, environmental rules, and service tools. Refrigerants are not interchangeable, and a system should not be topped off merely because heating or cooling is weak; leaks and system operation need qualified diagnosis.
Эта статья представляет собой практическое руководство по диагностике и закупке и не заменяет инструкции производителя насоса, утвержденный проект системы, действующие правила электромонтажников и сантехников или квалифицированное обслуживание на месте. Перед вскрытием оборудования отключите подачу энергии и сбросьте давление. Работы с колодцами, подъемные работы, работа в замкнутых пространствах, со сточными водами, во влажных электроустановках и испытания под напряжением требуют наличия компетентного персонала и средств контроля, соответствующих конкретным задачам.
Understand refrigerant versus trade name
Understand refrigerant versus trade name. Begin with the exact product, system, and operating condition rather than a generic assumption. For does a heat pump use freon, document the model, configuration, symptoms or objective, recent changes, and the instructions that control the work. Check the relevant supply, connections, controls, flow path, surrounding equipment, and environmental conditions in a safe sequence. Do not treat one observation as proof: compare it with a second measurement or an approved functional test. If the task exposes electricity, pressure, fuel, refrigerant, hot surfaces, contamination, moving machinery, or a vehicle safety system, stop and use qualified service. After any adjustment, restore guards and automatic protection, then repeat the same test and record the result. This makes the understand refrigerant versus trade name decision reproducible instead of relying on memory or trial and error.
Read the equipment label

Границы системы, диагностика и приемка
A heat pump is a refrigeration system, not simply a water pump. It moves heat by circulating refrigerant through a compressor, heat exchangers, expansion device, and reversing or control components. Electrical power use and operating behavior depend on outdoor and indoor temperature, building load, equipment capacity, efficiency, airflow or water flow, thermostat settings, auxiliary heat, defrost, installation, and maintenance. Nameplate ratings and standardized efficiency values do not by themselves predict one home's bill.
Refrigerant circuits are sealed, pressurized systems. Refrigerant identification, charging, recovery, leak repair, electrical testing, and component replacement require the approved equipment and appropriately qualified personnel. Do not vent refrigerant, heat a cylinder, open service valves, or defeat pressure, temperature, airflow, or defrost protection. A frozen coil, high bill, noise, or poor comfort can arise from airflow, filters, outdoor blockage, drainage, controls, sensors, duct or hydronic problems, weather, or building heat loss—not only refrigerant charge.
Useful records include model and serial numbers, system type, thermostat settings, outdoor and indoor temperatures, runtime, auxiliary-heat indication, filter and coil condition, airflow, condensate drainage, electrical consumption, service history, and fault codes. Compare similar weather periods. After service, verify stable heating and cooling, normal defrost, drainage, airflow, sound, protection, and documented refrigerant handling.
