Product Features

1. Copeland ZW series high-efficiency air supplement and enthalpy increase compressor (high-efficiency compressor designed for heat pump working conditions), realizing "quasi-two-stage compression" of air conditioning system, and one compressor realizing 2
stage compression
2. R410A green environmental protection refrigerant is adopted, which does not contain chlorine element that destroys the ozone layer. The refrigerant is stable in nature, non-toxic and has zero damage to the ozone layer (0DP is 0), and there is no prohibition period.
3. "TTSP" independent intelligent defrosting technology, the unit automatically determines the defrosting conditions, and truly realizes "more frost, more frost, less frost, less frost", defrosting is more accurate, water temperature fluctuations caused by defrosting are reduced, and the best energy-saving scheme is realized.
4. The fin non-uniform flow path design should deal with the uneven wind field (small air volume at the bottom, poor heat exchange, and non-uniform distribution to make full use of the heat exchange area), so that the wind side heat exchanger can play the best heat exchange capacity in actual application.
5, "supercooling ice suppression" design, the bottom of the fin heat exchanger has been flowing high temperature medium, can effectively prevent the winter defrosting water in the bottom of the fin freezing accumulation problem, to avoid its damage to the water collection tray and heat exchanger copper tube.
6. Imported high-performance electronic expansion valve, PID control automatic adaptation, air supplement control technology, exhaust temperature control technology, high stability, good adjustment, high accuracy, and full improvement system
The best performance of each 1 component within the system.
7. Efficient and stable heating at -35 ℃ low temperature environment. At the same time, multi-working conditions and multi-defrosting cycle reliability experiments, transportation experiments, water spraying experiments, noise experiments, etc. are carried out to ensure stable and reliable operation of the equipment.
8. Modular design, compact structure, small footprint, easy installation, and free combination according to needs.
