HIDROS was formed in 1993 as a distribution company operating in the humidication and dehumidication sector of the air conditioning market. The expansion was rapid and, as the knowledge of the market sector increased, opportunities for the development of specialist products were identied. The decision was therefore taken in 2001 to invest in a production facility and to manufacture their own design products. Since then, the company has added chillers, heat pumps and air handling units to its product portfolio.

Today, HIDROS with its qualied staff, designs, develops and tests heat pumps, water chillers, dehumidifying systems and air handling units all based on the refrigerant cycle. The total range of Hidros products includes standard dehumidiers with capacities from 25 to 3000 l/24h and heat pumps and water chillers with cooling and heating capacities from 5 to 1200 kW. In addition to this, HIDROS can offer a wide range of tailor made machines to meet any customer requirement. Expertise, quality, exibility and enthusiasm are the other essential elements of the company that ensure we provide a...

WHAT IS A HEAT PUMP? A heat pump is a device that moves heat from one location (called the 'source') to another location (called the 'user'), using a small quantity of high grade energy. Basically, a heat pump operates in a similar manner as an air conditioner, but in reverse. Expansion device HOW THE HEAT PUMP WORKS A heat pump comprises a refrigerant circuit, lled with a special uid (refrigerant) which, depending on the temperature and pressure conditions in which it is working, will be in either a gaseous or liquid state. The refrigerant circuit is made up of: • The compressor; • The...

THE SOURCE The external medium from which the energy is absorbed is called the source. It is generally a low grade (low temperature) source. In the heat pump the refrigerant absorbs heat from the source in the evaporator. The LZT, LZTi, WZT and LZi heat pumps use the ambient air as their source, and they are therefore identied as Air-to-Water heat pumps. The WZH and WHA heat pumps use water as the source and they are therefore identied as water-to-water heat pumps. THE USER For all Hidros heat pumps, water is the medium that is to be heated and this is called the user. In the heat pump, the...

• AIR TO WATER HEAT PUMPS; Air is used as the source. It has the advantage of being available at all times but with the disadvantage that, when the ambient temperature is close to or below 0°C, removal of heat will cause the heat exchanger to freeze and it is therefore necessary to incorporate a defrost system to clear the ice thus formed. Such a defrost system involves operating the 4 way valve to cause the refrigerant to pass in the opposite direction. This sends hot gas into the source exchanger and this melts the ice. Once the ice is clear, the heat pump reverses the valve again,...

• GROUND SOURCE HEAT PUMPS; In this case the source is the energy that is stored in the ground. Energy is absorbed from the ground by pipes through which brine (water/ glycol mixture), is circulating. The pipes can be installed either vertically or horizontally, depending upon which approach absorbs the max amount energy.Horizontal pipes are normally buried at 1 or 1.5 metres depth to avoid variations in temperature caused by changing ambient conditions whilst maintaining the advantage of the effect of solar radiation. As a guide, it is normal to have underground piping equal to 2-3 times...

EFFICIENCY OF THE HEAT PUMP During its operation the heat pump: • “Absorbs” electricity in the compressor; • “Absorbs” thermal energy from the source (air or water); • Releases thermal energy in the user heat exchanger (water). input energy, the unit will supply between 3 and 5 kWh of thermal energy to the user. The C.O.P. will vary and is dependant upon the temperature at which the heat is transferred (user), the temperature of the The main advantage of the heat pump is the capacity to supply more Energy (thermal) than that required for its operation (electrical). The efciency of a heat...
