Description
Technical Field
The invention relates to an indoor air medium aluminum calandria multi-source heat pump heating system, and belongs to the technical field of building heating.
Background
The air compression refrigeration cycle is composed of an air compressor, an expander or an expansion valve, a cold chamber heat exchanger and a water cooler, wherein an air medium runs in the air compressor, the expander or the expansion valve, the cold chamber heat exchanger and the water cooler in a closed mode. The low-pressure low-temperature air medium enters the compressor after being subjected to constant-pressure heat absorption in the coil heat exchanger of the cold chamber, is subjected to adiabatic compression by the compressor to increase the pressure and the temperature, then enters the cooler, is cooled to the temperature close to the atmospheric environment by the atmosphere or water, and then enters the expander or the expansion valve. The physical properties of the air determine the cooler's volume. The cold chamber heat exchanger is arranged outdoors and can absorb air energy but can not absorb solar energy and wind energy.
The air-air heat pump has evaporator set outdoor and fan to ventilate and the evaporator to absorb outdoor air energy. The condenser is arranged indoors, and the fan is used for forced ventilation to exchange heat energy emitted by the condenser into the room. The external medium of both the evaporator and the condenser is air. An air source heat pump air heater belongs to an air-air heat pump, and the heat pump is widely applied to houses and commercial buildings. The temperature difference between the internal medium refrigerant of the evaporator and the condenser and the external medium air is required to be realized, so that the evaporator, the condenser and the external medium air can exchange heat, and the energy efficiency of the heat pump is reduced. The internal medium refrigerant has greenhouse effect.
In 1852, thomson, professor uk first proposed a heat pump concept called a heat multiplier. A steam engine is used to drive an air suction cylinder and an air exhaust cylinder, and the working medium is air. The air suction cylinder sucks air from the outside (outdoors), sends the air into the air storage cylinder, and then sends the air into a building through the exhaust cylinder. In steady state operation, the air quantity sucked from the suction cylinder is equal to the air quantity discharged outside the building, otherwise, the air pressure in the building rises, and the building is not in a steady state. In steady state operation, the building exhausts air outwardly while taking away heat, reducing the energy efficiency of the "heat multiplier".
The document CN108917049A utilizes the feature that the air circulation heat pump simultaneously refrigerates and heats to precool the fresh air and provide heat for the reheating section, the fresh air and the reheating section belong to the same air channel, the heat energy effect of the air circulation heat pump 2 is the same as the heat energy effect of an electric heater which is added to the fresh air and the reheating section and has the same power as the electric power consumed by the air circulation heat pump 2, only one electric heater is needed, and the complicated air circulation heat pump 2 is not needed. The fresh air and reheating sections belong to an air processing functional section combination 1, heat generated by an air circulation heat pump 2 comes from two parts, one part is heat extracted from fresh air, and the other part comes from electric quantity consumed by an air compressor, which is equivalent to a direct electric heating mode. The document CN108917049A air circulation heat pump 2 exchanges heat only with the air handling functional segment combination 1, absorbs heat from the air duct, and sends the heat to the air duct, and the air circulation heat pump 2 does not exchange heat with the outside, and does not absorb heat from the outside except for consuming electric energy, and therefore, it is not a heat pump per se. The air-cycle heat pump 2 comprises an air compressor 21, a turbo compressor part 22, an air/water heat exchanger 23 and a circulating water pump 24, and more specifically comprises a reheating section 106.
The air source heat pump can not absorb solar energy, and the used refrigerant has greenhouse effect. The energy efficiency of the air source heat pump of the water system is further reduced by the temperature difference between the indoor heat dissipation system and the room temperature.
The solar air heat collector heats the air medium in the heat collector by using solar energy, and the air medium is normal pressure. The air heat collectors are classified into two types, namely non-permeable air heat collectors and permeable air heat collectors, according to the difference of the structures of the heat absorbing plates. The non-permeable air collector, which is sometimes called a non-porous heat absorbing plate type air collector, in the air collector, air flow does not pass through the heat absorbing plate, but flows on the front surface and/or the back surface of the heat absorbing plate, and exchanges heat with the heat absorbing plate heated by solar energy. The permeable air heat collector, sometimes called as a porous heat-absorbing plate type air heat collector, can be divided into different forms such as a metal wire net type, an overlapped glass plate type, a broken glass porous bed type, a honeycomb structure type and the like. The solar air collector can absorb solar energy, but cannot absorb air energy.
The aluminum calandria heat collector is arranged in an evaporation-compression-condensation heat pump, and a non-air heat transfer medium flows in the aluminum calandria heat collector.
