What are the Main Parameters of a Low Temperature Condensing Unit?

Low temperature condensing chillers are industrial refrigeration equipment that provide a stable low-temperature cold source. They operate through a cycle of compression, condensation, throttling, and evaporation, covering a wide temperature range from -80℃ to 200℃. Their core operating and performance parameters are mainly divided into the following categories:

1. Core Refrigeration Performance Parameters: These include nominal cooling capacity, evaporation temperature range, condensation temperature range, and Coefficient of Performance (COP). For example, 7-10HP models can achieve a minimum evaporation temperature of -45℃. COP directly determines the unit's energy consumption level under different operating conditions.

2. Structural and Power Parameters: These cover compressor type/power, refrigerant type, unit power supply voltage, and cooling method. Common models often use environmentally friendly refrigerants such as R410A, and support both 220V and 380V power supplies.

3. Operating and Safety Parameters: These include evaporation pressure, condensation pressure, refrigerant type, maximum operating pressure, and various alarm protection thresholds. Water-cooled models typically have a refrigerant-side pressure of up to 25 bar to ensure safe operation.

4. Appearance and Supporting Parameters: Includes unit dimensions, overall weight, circulating water flow rate, and interface pipe diameter, used for on-site installation layout adaptation verification.
