Heat pump for heating and cooling

Heat pump for heating and cooling

Heat pump for heating and cooling in the building, Hotel “LIBRIS”, SARAJEVO.

Heat pump for heating and cooling, the system consists of:

Outdoor unit.
Hydrobox - Indoor unit.
Hot water tank.
Tank for heating, cooling.

Solar panel collectors for heating and domestic hot water.

The heat pump for heating and cooling, and the plate solar collectors fully supply heating - cooling 16 apartments, kitchens, reception.

The heat bodies on the first and second are fan coilers.

Basement heating is done with Al PEX pipes - underfloor heating.

Heat pump in operating mode:


A heat pump (heat pump) is a heat machine by which heat energy is transferred from one medium to another.
The electricity in this process is mainly used to start the compressor.
This way, much less energy and money is spent on heat transfer.

The heat pump is fully automatic and requires no monitoring.
A heat pump is a device that is fully customizable for:

heating and cooling of residential, commercial and other buildings.

There are basically 2 types of heat pumps:
- Heat pump air - water
 Water - water heat pump.

Air - water heat pumps,
they use air-to-air energy as a source of energy.

How does a heat pump work?

An air source heat pump has three cycles:
heating,cooling cycle and defrost cycle.

The heat pump cycle is completely reversible and heat pumps allow heating in winter and cooling in summer.

Water - water heat pumps use water energy as a source of energy.

New generation heat pumps operate efficiently at extremely low temperatures up to -25 C, at such a low temperature the COP efficiency level is lower (2.2), while at a temperature of 0 C the efficiency level is 3.8-4.0.
That is an indication that the investment in heat pumps is worth it, because for 1kWh of electricity you get through the heat pump assembly up to 4kWh of heat energy.

Heat pumps are very efficient heating and cooling systems, and can significantly reduce energy costs.

However, before investing in the procurement and installation of a heat pump, it is necessary to insulate the heated building (by insulating: walls, ceilings, windows, doors, etc.).
