Thermodynamic Solar Heat Pump
A Gen-Next Heat Pump Technology

The Thermodynamic Solar System joins two incomplete technologies, the heat pump and the solar thermal collector. Heat pumps are quite efficient equipment but the heat they produce from their renewable component varies only according to changes in the temperature of the environment.

Thermal solar collectors are the best source of heat on hot and sunny days, but they are totally inefficient whenever there is no sun.

The thermodynamic Solar Technology manages to surpass the limitations of both the heat pump and solar collector. Through the cooling liquid (R134a or R407c ) which covers a closed circuit, the liquid goes into the solar panel and extract the thermal energy of sun , rain, wind, environment temperature and other climate factors . During this process the liquid gains heat in a more favorable way than a heat pump. after this stage , the heat it transferred to an exchanger with the help of a small compressor, which heats the water , The liquid cools down and the circuit is repeated.

As the fluid has a boiling temperature of approximately -30C , the system works even when there is no sun and it even works at night, hail, rain, wind or shine , unlike the traditional solar thermal system.
The energy consumption of the system is basically the same as fridge compressor that makes the liquid circulate. there are no ventilators that help the evaporation process, of defrost cycles, which imply unnecessary energy consumption, unlike what happened with heat pump

Hot water for You ……
Any time , Any where Any Weather

The Thermodynamic Solar technology offers high performance even at night, with rain, or on overcast days, this being an advantage over conventional solar panels whose performance is limited as they rely exclusively on direct solar radiation and a compulsory southward orientation (Northern Hemisphere).

The Vindsol Thermodynamic solar system guarantees the production of hot water for domestic, commercial and swimming-pools providing the maximum energy efficiency 24 hrs a day, thanks to its revolutionary working principle.

The Vindsol TDHP systems deliver energy efficiency solutions for the applications in the public and private sectors.

Most Advanced Solar Assisted heat pump
Most Energy Efficient performance
Very Low on maintenance
Long life span Highly durable (no glass or Glycol).
Absorbs energy from sunlight, wind and rain.
Very light and easy to install.
Normally fitted to a wall (can fit to roof).
Can be fitted on any wall, doesn’t need direct sunlight.

Thermodynamic Solar panel - The Soul of Thermodynamic solar heat pump.

Life span of more than 10-15 years: the panel is made of anodized aluminum 30 micron, which ensures The following properties

  • Great toughness at high and low temperatures.
  • High surface hardness.
  • Resistance to abrasion and weakening.
  • High protection against dust and dampness.

Latest generation thermodynamic solar collector: it is a roll-bond panel with double channel through which the fluid refrigerant circulates, being able of providing high performance at night and in adverse climate conditions.

User-friendly transport and easy handling systems: small size 2 m x 0,8 m.

Versatility: easy integration on facades, roofs or any other surface. It is not necessary to reinforce structures as it is a lightweight panel, 8 kg.

Optimized solar catchment area: both sides of the panel, 3,20 sqm.

No need to be south orientated (Northern Hemisphere). Vindsol recommends to orientate the collector as much as possible to the sun and exposed to the elements, such as wind and rain.

Regular maintenance is not necessary.

We use Only Heat pump Specific designed Compressor

The entire range of Vindsol heat pumps uses heat pump specific compressor and not the Air conditioning compressor which is predominantly used in the market.

Superior features of Heat Pump Specific Compressor

The compressors are required to be operated under the conditions of high flow and high load in summer, and under the conditions of low flow and high-pressure ratio in winter.

The Heat pump specific compressors are uniquely designed with higher compression ratios and larger pressure difference, allowing for systems to operate under wider conditions compared to ordinary heat pump or air-conditioning compressors. Equipped with high efficiency and high-power motors, our compressors meet the toughest challenges for heat pumps and water heaters even in the harshest ambient conditions.

It has higher condensation temperatures complementing the heating of water up to 65 deg, whereas the regular air conditioning compressor has condensation temperature of 45 degrees..

Domestic Range : The Compressor used in the domestic applications up to 8 KW of heating range is rotary type.

Commercial Range: Heating capacity range from 12 Kw and above uses Copeland ZW range of heat pump compressor

Thermodynamic Heat Pump Working

Stage 1

A thermodynamic panel is fitted to the outside of the property, usually on a south facing wall or roof.

Stage 2

The fluid refrigerant enters the panel at -10ºC that changes its state due to the heat previously captured from the ambient temperature which is present in the direct and diffuse solar radiation, external air by natural convection, wind effects and rainwater.

Stage 3

The hot gas comes out of the panel and goes into the compressor that increases the refrigerant gas temperature up to 120ºC

Stage 4

The heat is released into the water tank through a heat exchange coil to a maximum temperature of 55° C.

Stage 5

As it cools after transferring heat, the refrigerant condenses into liquid and flows through the expansion valve that measures the amount of the liquid refrigerant that will be sent to the panel. Thus the cycle starts all over again.
The system uses a small amount of electricity to run but mostly relies on the ambient heat outside. For every unit of electricity used, the system will generate 3 – 6 units of heat for your home.
