(4). waste heat recovery air source heat pump for heating/cooling/DHW (for weather temperature min. -7, or weather temperature min. -25) The air-to-water heat pump is intended for use in existing or newly built heating systems. The heat pump is designed for the cooling, heating for heating purposes and the supply of domestic hot water! The heat pump is suitable for mono-energetic and bivalent operation. Defrosting of the evaporator is automatic. In winter, the air is the heating source, the heat pump can get heat from the heat source by the compressor circuit, and the heat can be transferred into the room through water, so the room becomes warm. In summer, the air is the cooling source, the heat pump can get heat from room by the compressor circuit, and the heat can be transferred into the cooling source through water, so the room becomes cool. The heat pump can supply domestic hot water every time, even if when cooling. In summer, DHW is heated from the waste heat that should be sent to air, so the heat of DHW is free. DDR series heat pump delivers heat up to a fixed temperature level. This is called “fixed condensing”. DDR series heat pump can be docked to an external unit with its own heating controls, for example, room thermostat for floor heating system or thermostatic valve for radiator. 1.

(1) ground source heat pump for heating(brine to water) (2) ground source heat pump for heating/DHW(brine to water)

Ground source heat pump technology implements transferring the low-temperature from earth's

surface shallow water (river, lake, sea)and Soil that absorption of solar energy and geothermal energy,

to high-temperature by importing a little of electricity. Ground source heat pump can supply cooling,

heating and domestic hot water.

DISMY ground source heat pump is a heating system which is designed for operation as brine/water

heat pump. The heat pump extracts energy from the heat source medium at a low temperature level.

This extracted energy is then transferred to the heating water at a higher level, enriched with the

energy transferred by the compressor. Subject to the heat source temperature, the heating water can

be heated up to a flow temperature of 55 .℃

A three-way valve built-in（optional） have been integrated for diverting the flow either to the heating

circuit or the DHW circuit. DHW is heated by pumping the heating water, which has been heated by

the heat pump, through a heat exchanger into the DHW cylinder, where it transfers its energy to the

DHW. DM2066 DHW thermostat can be used to start DHW function instant or by timing.

DDR series heat pump delivers heat up to a fixed temperature level. This is called “fixed condensing”.

DDR series heat pump can be docked to an external unit with its own heating controls, for example,

room thermostat for floor heating system or thermostatic valve for radiator.

(6) water source heat pump for heating(water to water) (7) water source heat pump for heating/DHW(water to water)

Water source heat pump technology implements transferring the low-temperature from groundwater

that absorption of solar energy and geothermal energy, to high-temperature by importing a little of

electricity. Water source heat pump can supply cooling, heating and domestic hot water.

DISMY Water source heat pump extracts energy from the heat source medium at a low temperature

level. This extracted energy is then transferred to the heating water at a higher level, enriched with the

energy transferred by the compressor. Subject to the heat source temperature, the heating water can

be heated up to a flow temperature of 55 .℃

A three-way valve built-in（optional） have been integrated for diverting the flow either to the heating

circuit or the DHW circuit. DHW is heated by pumping the heating water, which has been heated by

the heat pump, through a heat exchanger into the DHW cylinder, where it transfers its energy to the

DHW. DM2066 DHW thermostat can be used to start DHW function instant or by timing.

DDR series heat pump delivers heat up to a fixed temperature level. This is called “fixed condensing”.

DDR series heat pump can be docked to an external unit with its own heating controls, for example,

room thermostat for floor heating system or thermostatic valve for radiator.

(7) water source heat pump for heating/cooling (water to water)

Water source heat pump technology implements transferring the low-temperature from groundwater

that absorption of solar energy and geothermal energy, to high-temperature by importing a little of

electricity. Water source heat pump can supply cooling, heating and domestic hot water.

DISMY Water source heat pump extracts energy from the heat source medium at a low temperature

level. This extracted energy is then transferred to the heating water at a higher level, enriched with the

energy transferred by the compressor. Subject to the heat source temperature, the heating water can

be heated up to a flow temperature of 55 .℃

A three-way valve built-in（optional） have been integrated for diverting the flow either to the heating

circuit or the DHW circuit. DHW is heated by pumping the heating water, which has been heated by

the heat pump, through a heat exchanger into the DHW cylinder, where it transfers its energy to the

DHW. DM2066 DHW thermostat can be used to start DHW function instant or by timing.

DDR series heat pump delivers heat up to a fixed temperature level. This is called “fixed condensing”.

DDR series heat pump can be docked to an external unit with its own heating controls, for example,

room thermostat for floor heating system or thermostatic valve for radiator.
