Embodiment approach 1

[0028] Embodiment 1: A cold source is provided for the front heat exchanger 3 and a heat source is provided for the rear heat exchanger 4 at the same time. Depending on the cost and convenience of the user's access to the cold source, the cold source of the front heat exchanger 3 can choose chilled water, cooling water, ground source cold water, cold storage chilled water, etc., and the heat source of the rear heat exchanger 4 uses the condensation of the refrigerant For heat protection, the rear heat exchanger 4 is used as a heat pump condensation coil. The air to be processed passes through the pre-heat exchanger 3 and conducts indirect heat exchange with it, which can realize cooling and dehumidification or isohumidity cooling and other processes. Overcome the local resistance of the front heat exchanger 3, enter the rear heat exchanger 4, and then perform indirect heat exchange with it, so that iso-humid heating can be realized. When the air to be processed passes through...

Embodiment approach 2

[0029] Embodiment 2: Provide the cold source for the front heat exchanger 3 and provide the cold source for the rear heat exchanger 4 at the same time. The cold source of the pre-heat exchanger 3 can be selected from chilled water, cooling water, ground-source cold water, cold storage chilled water, etc., and the cold source of the rear heat exchanger 4 is refrigerant. The treated air undergoes secondary cooling and dehumidification, which greatly increases the cooling capacity and lowers the outlet air temperature, which can realize deep dehumidification and large temperature difference air supply.

Embodiment approach 3

[0030] Embodiment 3: Provide the heat source for the front heat exchanger 3 and provide the heat source for the rear heat exchanger 4 at the same time. Depending on the cost and convenience of the user's access to the heat source, the 3 heat sources of the pre-heat exchanger can choose urban heat pipe network, vortex furnace hot water, waste water, ground source hot water, electric hot water, solar hot water, and other heat sources. Water, etc., the heat source of the rear heat exchanger 4 is used to prevent heat from condensation of the refrigerant, and the rear heat exchanger 4 is used as a heat pump condensation coil. The treated air is heated twice, the heating effect is high, the outlet air temperature is greatly increased, and the air supply with large temperature difference can be realized.

[0031] In addition, if only the cold source is provided to the front heat exchanger 3 or the rear heat exchanger 4, the ordinary single-energy refrigeration and dehumidification ca...

Abstract

The invention solves the problem that the current room air conditioner use is single, the function is simple, the application range is limited, the invention provides a kind of double-energy source room air conditioner device, it includes thermal retardation box, electric machine, centrifugal fan, defrosting pan, wind outlet, it especially sets a heat exchanger at one side of the centrifugal fan, it sets heat exchanger between the front heat exchanger and the wind outlet, the front heat exchanger is made up of connected pipes, the back heat exchanger is made up of wind back pipe connected with the allocating device, the energy source media for front heat exchanger and back heat exchanger are cold / boiled water and cold-producing agent.

Description

technical field [0001] The invention relates to an indoor air conditioner, in particular to an indoor air conditioner capable of providing dual energy media. Background technique [0002] The existing central air-conditioning terminal equipment, the ordinary horizontal concealed fan coil unit, only has a single heat exchanger and only provides a single energy medium. The heat exchanger is generally composed of copper tubes and aluminum sheets, and the water inlet and outlet for energy supply are usually on the same side. The heat exchanger can be used as a surface cooler or a heater. With the development of household central air conditioners, some manufacturers have changed the way of the liquid inlet and outlet joints of ordinary horizontal concealed fan coils. The heat exchange coils have been strictly cleaned, and ordinary horizontal concealed fan coils have been transformed into refrigerants with energy as refrigerant. Fan coil unit, or ducted...
