HEAT PUMPS

1. Open system – it uses directly pumped out water from sounding,  well, lake or river. In regime of heating, the pumped out water enters into ZTK and gives part of its heating energy to the freezing agent and already chilled it comes back to second sounding, lake or river. In regime of refrigeration, water takes heat from freezing agent and leads it to the ground.

2а. Closed system – anti freezing solution is circulating in polythene pipes, which are laid in vertical sounding or horizontal ditch, sea, river, lake, marsh or canal. In winter, the anti freezing solution takes a heat from the ground or water, and gave it away into the heating rooms through the medium of ZTK. In summer it’s the opposite – the heat is going from the rooms, into the ground.

2б. Closed system with direct enlargement - freezing agent /R22, R407C/ from ZTK is circulating and evaporate to copper pipes, which are laid in the same way like closed manner.

How ZTK Geosolar is connectied to the rooms?

1. Air heating and \ or refrigeration. In usage are Freon convectors just like in usual air-conditioners. It’s suitable for two rooms limitary.
2. Water heating and \ or refrigeration. It’s suitable for more than two rooms.
а. Heating: from the floor or wall and water pipes heating, water convectors, through ordinary cast-iron or aluminium radiators.
