heat pump water heater

EVI monobloc air to water heat pump

Introduction

Goldsun EVI heat pump doesn't actually generate heat.It simply transfers the energy from the air to water. Air passes the evaporator filled

with a very cold refrigerant. Heat from the air is absorbed by the refrigerant,which is then pushed through the heat pump by compressor and

transferred to water by heat exchanger. .It's wildly used in the place of House,Hotel,School,Factory,Hospital,Office,SPA,Aquarium,Supermarket

etc.For its advantages of Green,energy saving,safe, Goldsun Ground Source Heat Pump is the best choice of heating device you ever have today!

Main components

1. Heat pump special design EVI compressor of Hitachi or Sanyo enable stable high pressure output and operation, low noise and high efficiency

(fastly heat and cool) even in tough environmenal temp.of -25 °C.

2. Condenser of special design (spiral shape) or Germany GEA AISI 316 stainless steel plate with high heat exchange efficiency, avoid scale to have

a longer working life.

3. High quality America Emerson Alco expansion valve to have accurate and sensitive thermal control.

4. Evaporator of Hydrophilic fin coil to avoid forming water drop and make good heat interchange.

5. High quality Japan Saginomiya 4 way reversing valve enable a easy reversing of refrigerant and defrosting.

6. Galvanized steel with powder painted housing with anti-erosion to make a fresh outlook and long life and can be installed in salty air territory.

7. High quality LED Intelligent controller provide heat pump with temperature,compressor, pump, defrosting control; compressor extension, high/low

pressure, low in water, over heat air exhaust protection; preset on/off, self-test function.

8. Base frame and external panels made of galvanized powder coated steel

9. Experienced workmanship and apply lean manufacturing with a rigid assembly line procedure together with overall QC general test to get a high quality

complete unit before package in the factory

10. Cooperated with Scientific and research agent makes us up-to-date technology and good, stable operation performance.

Optional:

1. Controller of Siemens,Italy ElWELL, CAREL available for Remote keyboard ( indoor control panel).

2. Plate heat exchanger of Sweden SWEP. 2. Germany WILO water pump and SIKA water flow switch from Germany ensure the good quality product.

.

Comparison of components

1.Exchanger: we use hydrophilically coated heat exchanger prevent debris sticking to it and is with nice color and high efficiency; Others use common heat heat exchanger

which is not hydrophilically coated is with low heat exchanger efficiency.

2. Metal plate: we select excellent plate whose thinkness is enough (1.55MM) and can resist correction for use Grade 1 galvanized and superior static coating; Others use

common metal plate (0.82MM)

3. TEV: we use the imported pure copper TEV adopted by Goldsun, which could automatically adjust heating output, can ensure our unit run stably and effectively.

Others use common capillary could not control the heating output automatically.

4. Electronic expansion valve: we use Alco with accurate control of refrigerant flow is moreenergy-efficient.Others use common EEV without accurate control is

less energy-efficient.

5. Non-CFC insulation: we use high density foaming insulation with good heating protection.Others use low density foaming insulation which is without good heating protection.

6.Wire terminal: we use maintenance-free terminal can avoid bad contacting by vibration and oxidation, thus makes electric fault decrease largely by 50%.

7. Electrical box: designed with water proof and easy to open, With circuit breaker switch inside. It is safe and convenient for maintenance.

8. Fan: we select the axial fans, which can bring heavy wind and with less running noise.
