Product Description

Brief introduction
This series of air source heat pump is designed for the common area of ambient temperature between -30 °C, to 46°C, .
The unit is designed for residential sanitary hot water of bathroom, kitchen etc. or offering central heating(radiator/floor heating) to houses, or commercial building, for example, hotel, school, hospital, hair salon, etc.
In the mean time, cooling function for air conditioner is for optional.
 
This unit could be installed in outdoors, as floating support for compressor to reduce vibration at the most extent and noise insulation inside the cabinet as well as noise jacket for compressor.
The compact design  heat pump is built-in Copeland  scroll type compressor ,Deron made coaxial coil heat exchanger, Emerson thermal expansion valve and Saginomiya four-way valve to ensure it work smoothly and efficiently.

Product Features
• With suction gas cooled scroll compressor.
• With extensive hydrophilic coating aluminum/Cu lamellar tube evaporator and coaxial condenser.
• Axial fan
• Refrigerant cycle with thermostatic expansion valve, filter, gas-liquid separator, high and low pressure switches.
• With efficient automatic defrosting by hot gas principle.
• Electric and terminal box. With control and disturbance signaling.
• Heating regulator for mounting to the wall.
• Stable water flow switch is optional.
• Filled with refrigerant R410a.Other Eco-friendly refrigerant like R134a, R417a etc. is available.
• Auxiliary electric heater or solar coiler is optional as a back up heater.
• Strict noise control. Floating support for compressor
 To reduce vibration at the most extent and sandwich noise insulation inside the cabinet and noise
preventing jacket for compressor.
Water connections
• Water connections have to be done on site.
• Heating and condensate connections of flexible pipes with external thread (R).
Condensate connection
• The drain pipeline is to be made with sufficient incline and without change of the crosssection.
• The water connections and the drain pipelines must be protected against frost on site.
• Siphon on site.
Heat source connections(Air intake or air outlet)
• Air intake from sides. Air outlet from the top.
Electrical connections
• Connection from the bottom to the left or to the right.
Installation
• Variable and cost-efficient installation possibilities.
Delivery
.• Complete, well packed(Every unit will be tested to ensure the superior quality and feature before package).
