Multi-function air conditioner

Abstract

The invention relates to a multifunctional air conditioner. An air cooling compression type air conditioner (2) and a heating water heater (3) are installed in an outer casing (1), the air cooling compression type air conditioner (2) is connected with a valve (5) and the heating water heater (3) through a pipe in parallel, the heating water heater (3) and the valve (5) are connected with a peripheral fan coil (7) through pipes in parallel, the input end of the air cooling compression type air conditioner (2) is connected with the output end of the peripheral fan coil (7) through a pipe, and the circuits of the air cooling compression type air conditioner (2) and the heating water heater (3) are respectively electrically connected a controller (6). The air conditioner has the advantages that the thermal efficiency is high, the refrigeration effect and the heating effect are good, the air conditioner is not influenced by the indoor low temperature, the occupied indoor space is small, theoperating cost is low, the energy resource is saved, the operation is convenient, and the market prospect is good.

Description

technical field [0001] The invention relates to a multifunctional air conditioner capable of cooling, heating and providing sanitary hot water. Background technique [0002] The small electric air-cooled compression heat pump air conditioner in the prior art, also known as the household central air conditioner, has been widely accepted as refrigeration and heating equipment. However, since this kind of air conditioner is greatly affected by the outdoor temperature when heating, when the outdoor temperature is 0-3°C, its energy consumption for defrosting is as high as 60%, so that the indoor temperature actually does not reach the set standard. The heating effect is reduced, and the operating cost is often increased. Therefore, in recent years, there has been an improved method and product that can use an air conditioner for cooling, a water heater for heating and provide sanitary hot water. However, although the heating effect of this improved method and product has been im...

Problems solved by technology

However, since this kind of air conditioner is greatly affected by the outdoor temperature when heating, when the outdoor temperature is 0-3°C, its defrosting energy consumption is as high as 60%, so the indoor temperature actually does not reach the set standard Reduced heating effectiveness and often higher operating costs

Therefore, in recent years, there has been an improved method and product that can use an air conditioner for cooling, a water heater for heating and provide sanitary hot water. However, although the heating effect of this improved method and product has been improved, its functions have also increased. , but because the two sets of systems have different terminal equipment for cold and heat exchange, the air-conditioning system can only use strong exhaust fan coil units for cold and heat exchange, while the heating system must use convective radiation radiators for cold and heat exchange, Therefore, the disadvantages of system overlap, large investment, large space occupation, and inconvenient operation are caused, which seriously hinders the market development of this product.
