The utility model discloses still be equipped with the cross valve in, it is the same with the theory of use of the cross valve on current air conditioner, the air source water heater host computer.

The utility model discloses a four kinds of mode:

mode one, hot water production outdoor air circulation flow: the process is that the outdoor electric air valve is opened firstly, the outdoor air passes through the nano silver filter screen, namely the metal filter screen, flows through the lower working cavity of the host where the compressor is located, then passes through the evaporator with the silver nano coating, the outdoor gravity self-closing air valve is blown open by the outdoor fan, at the moment, the indoor electric air valve is closed, the indoor fan does not work, and the indoor gravity self-closing air valve is closed. In the first mode, the compressor drives the evaporator and the heat preservation water tank to work, refrigerant circulation is achieved through the refrigerant coil, air flows and changes cold air through heat exchange with the evaporator, the refrigerant exchanges heat with water in the heat preservation water tank at the refrigerant coil, the water temperature in the heat preservation water tank rises, hot water is provided for indoor heating and air conditioning, a water inlet of a domestic hot water coil on the heat preservation water tank is connected with a domestic tap water pipe, tap water flows through the domestic hot water coil to exchange heat with hot water in the heat preservation water tank, and original cold tap water in the hot water coil becomes hot water to provide fresh hot water for a house.

Mode two, air circulation flow in the refrigeration air chamber: the process is that an indoor electric air valve is opened, air in a room passes through a high-efficiency filter, flows through a compressor and an evaporator, an indoor gravity self-closing air valve is blown open by an indoor fan, the heat exchange condition is the same as that of the mode I, water in a heat preservation water tank is heated, and the indoor air is cooled. If the air-conditioning mode is carried out for a long time, the high temperature of the heat-preservation water tank can lead the compressor of the main machine to start high-temperature high-pressure protective shutdown, and at the moment, the control main board can start the circulating pump and the outdoor air disc machine connected with the heat-preservation water tank in advance to reduce the water temperature in the heat-preservation water tank according to temperature feedback information; the water tank cover of the heat-preservation water tank can be manually operated to be adjusted through the rotating shaft, so that the heat discharge pipeline of the water tank cover and the eccentric port at the top of the tank body are correspondingly subjected to heat dissipation, and hot water in the heat-preservation water tank is subjected to heat dissipation; the hot water in the hot water coil pipe can be connected to various domestic water points, and the water temperature of the water tank can be reduced due to the fact that hot water is used in summer, such as showering, washing hands, flushing toilets, washing clothes, washing mop, washing dishes and vegetables, and the like.

In the second mode, a reverse running mode is adopted, and only the reversing of the four-way valve of the main machine is controlled to achieve the purposes of cooling hot water in the water tank and blowing hot air indoors. When the air conditioner runs reversely, the circulating pump and the outdoor air disk machine are not started, and the ultraviolet sterilizing lamp, the negative ion generating device and the nanometer water ion device are combined and selectively started in the process of air conditioning or reverse running mode, so that the aims of filtering dust and dirt from indoor air and sterilizing are fulfilled.

Mode three, the mode of taking a breath is by indoor to the outdoor foul air that discharges, and the compressor work is hot water simultaneously: the process is that an indoor electric air valve is opened, an outdoor fan is started, air exhausted from the indoor blows an outdoor gravity self-closing air valve under the air exhaust effect of the outdoor fan, the indoor fan is closed, namely the indoor gravity self-closing air valve is closed, the outdoor electric air valve is closed, the hot water making process is in the same mode, at the moment, negative pressure can be generated in the room, partial fresh air is supplemented through gaps of a room enclosure structure or opened doors and windows, and the air exchange function is achieved.

Mode four, the new trend is promptly by outdoor to indoor fresh air that send, compressor work, system hot water simultaneously: the process is that the outdoor electric air valve is opened, the indoor fan is opened, the indoor gravity self-closing air valve is blown open under the action of the indoor fan, the outdoor fan is closed, namely the outdoor gravity self-closing air valve is closed, the indoor electric air valve is closed, and the hot water making process is in the same mode as the first mode. The indoor dirty air can be partially discharged by the gap of the house enclosure structure due to positive pressure, and a far end in the air flow direction can be provided with an outdoor exhaust device or a door and window opening device to achieve a better fresh air effect. In the process, the ultraviolet germicidal lamp, the negative ion generating device and the nanometer water ion device can be combined and selectively started like the mode II to achieve the aims of filtering dust and dirt, sterilizing and disinfecting by fresh air. In winter, the four-way valve of the main machine can be controlled to change direction, namely, the reversing operation mode is used for sending warm fresh air to the indoor space.

The utility model discloses a concrete implementation mode:

the utility model discloses under the condition that external wall insulation is good, door and window gas tightness, heat preservation and heat insulation nature are high, no matter single-body house, still commodity room suite all can use as central air conditioning the same and have the water heater function again concurrently, save investment cost.

In the first application scenario, a host and a heat-preservation water tank can be placed indoors, three holes are formed in the wall, an outdoor air inlet is communicated with an outdoor electric air valve on the host through an air pipe from bottom to top in sequence, an outdoor air outlet is communicated with an outdoor gravity self-closing air valve on the host through the air pipe, and a natural convection heat dissipation port of the water tank is communicated with a heat dissipation pipeline on a water tank cover through a pipeline. The main machine and the heat preservation water tank are arranged on two sides of the toilet of the commodity room, and the main machine and the heat preservation water tank can be integrated with the wardrobe into a whole because a room wardrobe can be made by a general house owner, so that the main machine and the wardrobe cannot be seen after decoration, the space is saved, the cost is reduced, the appearance is attractive, the main machine is convenient to discharge condensed water, heat preservation water tank overflow, accidental water leakage and water drainage after unpicking and washing close to the toilet, and the main machine and the.
