However, the heat generated while operating in the heating mode is delivered to a hydronic distribution system within the building. When operating in the cooling mode, air-to-water heat pumps deliver a stream of chilled Figure 4-1 water, or chilled antifreeze solution, that flows to the balance of the system. The use of a hydronic distribution system for heating and cooling creates many possibilities that are not possible with forced-air distribution systems. MONOBLOC AIR-TO-WATER HEAT PUMPS Figure 4-1 shows a modern “monobloc” air-to-water heat pump. The insulated pipes, seen penetrating the building wall behind the unit connect to the interior portion of the system. When operating, variable-speed fans pull outside air across the air-to-refrigerant heat exchanger on the rear of the unit. In heating mode, this heat exchanger serves as the evaporator. Low-temperature heat is absorbed from the air, and the cooled air is discharged through the fan grills at the front of the unit. In cooling mode, the same heat exchanger serves as the condenser for dissipating heat to outside air. Monobloc air-to-water heat pumps house all the refrigeration system components and most of the electrical controls within the outdoor unit. Some monobloc heat pumps also contain hydronic components such as a circulator, expansion tank or flow verification switch. Monobloc heat pumps are supplied pre-charged with the correct amount of refrigerant, which implies that they can be installed without need of refrigeration service equipment. Figure 4-2 illustrates the basic internal components in a monobloc heat pump as they would operate in heating and cooling modes. 28 condenser evaporator evaporator condenserPDF Image | Heat Pump Systems 2020
