Product Description

Commercial Mini Air Source Heat Pump Air Conditioning

Characteristics

Structure: Panels and base frame are made from galvanized steel protected with polyester powder painting to ensure total resistance to atmospheric agents.
Compressor: Hermetic scroll type compressor, equipped with the crankcase heater and thermal protection with thermal overload cut-out and crankcase heater mounted on rubber vibration isolators.
Axial fan: External rotor type axial fans, equipped with single phase direct drive motors, low noise 6 poles, protection level IP54, provided with a protective outlet grille.
Evaporator: High efficiency and low pressure drop stainless steel (AISI 316) water exchangers, with anti-freeze heating element (option) and differential pressure switch, factory insulated with flexible close cell material.
Condenser: Coils are consisting of seamless copper tubes mechanically expanded into blue hydrophilic aluminum fins, 100% fully quality tested; sub cooling circuit to prevent freezing at the base (optional); protected with metal grill.
Desuperheater: High efficiency stainless steel brazed plate heat exchanger, factory insulated with flexible close cell material (optional).
Refrigerant circuit: Copper tube connection with charge valve, filter, sight glass, gas-liquid separator, thermostatic expansion valve, low pressure switch with automatic reset, high pressure switch with manual reset. The heat pump unit is completed also with 4-way valve, liquid receiver and one way valve.
Water circuit: Built with air vent valve, water drain connection, and female-threaded hydraulic connectors.
Water pump (8kW-30kW), differential pressure switch.
Expansion tank (8kW-30kW).
Electric panel: Consists of:
- Compressor contactor
- Compressor protection breaker
- Fan motor protection breaker
- Control circuit protection breaker
- Phase sequence relay (only for 3-phase)
- Programmable microprocessor controller
Optional:
- Additional electric heater embedded in the coils for defrosting in low temperature ambient. It must be factory installed.
- Stainless steel covering
- Remote condenser
- Tube in tube heat exchanger
- Water circuit electric heater
