zhengxu heat pump parts

Parts comparision with heat pump of other brands

compressor

(COPELAND)World famous American COPELAND Compressor: High efficient, Reliable quality,Anti-wear-out nature,Long life-span,Low noise,Over-currency protection,Over-heat protection,High and low voltage protection.  

Compressor of other brand: No merits of Copeland and can’t optimize the cryogen’s working capacity.

condenser

Serpent Shape condenser: Enlarged contact area comapring with common types.The heat exchanging efficiency increase. Water circulating design eradicates water scales. Longer life-span and easy maintenance

Condenser used in other brands are smooth surface copper tube or flat shape s/s. The exchanging area is small at about 3.Lower working efficiency and higher electricity consumption than serpent shape condenser.

speed and volume controlling equipment

E-expansion valve: cryogen’s flowing speed is controlled by e-signal. It increases working efficiency greatly (-10~45).The total cost for whole equipment increases as well.

thermodynamic expansion valve:cryogen’s pressure release and temperature are sensed by this valve.Speed is slow and working environment is at 5~35.Its cost is comparatively low as well.

evaporator

Double-line enlarged evaporator: Evaporating area is 1.5 times of common heat pump.Cryogen’s evaporating speed is fastened.Cost is 1.5 times of common heat pump.

Single line evaporator: Small evaporating area and slow evaporating speed. Heating exchanging efficiency is very low

ventilation system

Single high efficient fan: Ventilation system is large. Increase cryogen’s evaporating speed and efficienty

Two low efficient fans.Two fans affect each other and reduce ventilation volume, Heat exchanging efficiency is low.

warm-keeping   tank

S/S foam tank: Interior layer is 0.8MM s/s.Outside layer is 0.6MM s/s. Middle stuffing is 50MM foam.Super warm-keeping guarantee. No more than 2 celsius dropping within 24 hours. Cost is 1.5 times of common water tank

Common water tank with interior layer S/S 403 at 0.5mm and outside layer zinc alloy at 0.3 mm. Temperature can drop at 5 celsius within 24 hours. Its cost is verylow
