Water tower applied to water source heat pump air conditioner

Abstract

The invention relates to a water tower applied to a water source heat pump air conditioner. The water tower comprises a tower body; a water return pipe; an impounding reservoir arranged in the tower body; an air distribution device, a water spray filler, a water distribution device, a water collector and ventilation equipment which are arranged above the impounding reservoir in sequence; and a supply pipe with two ends respectively communicated with a water source inlet of the water source heat pump air conditioner and the impounding reservoir. One end of the water return pipe is communicated with a water return outlet of the water source heat pump air conditioner, and the other end is provided with two branch pipelines; one branch pipeline is connected with the top of the tower body through a gate valve and communicated with the water distribution device; and the other branch pipeline is connected with the bottom of the tower body through a gate valve and communicated with the impounding reservoir. The water tower applied to the water source heat pump air conditioner reduces the influence of the external environment on the water return temperature in winter, guarantees the normal heating of the water source heat pump air conditioner, relieves the compressor burden of the water source heat pump air conditioner, reduces the energy consumption, and prolongs the service life of the water source heat pump air conditioner.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a water tower applied to water source heat pump air conditioning. Background technique [0002] Water source heat pump air conditioner is a low-carbon energy-saving air conditioner developed in recent years. Its biggest feature is to change the external air conditioner with strong exhaust and heat dissipation to a built-in central water cooling system. [0003] Existing water towers used in water source heat pump air conditioners generally include a tower body, a water storage tank, an air distribution device, a water spray filler, a water distribution device, a water eliminator, ventilation equipment, a cooling return pipe, and a supply pipe. The water reservoir is arranged at the bottom of the tower body, the air distribution device is arranged above the reservoir, the water spraying packing is arranged above the air distribution device, the water distribution device is arranged...

Problems solved by technology

Therefore, due to the above-mentioned structure of the existing water tower used in the water source heat pump air conditioner, it can only provide the function of heat exchange and cooling. Therefore, in winter, when the existing water source heat pump air conditioner needs to exchange cooling and heating, the compressor inlet water temperature of the air conditioner will It must be kept above 16°C to provide normal heating. At this time, the return water in the return pipe needs to be kept warm or even heated instead of cooled.

Especially in winter when the weather is cloudy and rainy, the low outside temperature will directly affect the temperature of the return water. When the water temperature is below 16°C, the structure of the existing water tower used in water source heat pump air conditioners will expose the return water to low temperature air, and Due to the long loop of the return water, the temperature of the return water is more likely to be affected, and it is difficult to meet the minimum water temperature standard for heating of the existing water source heat pump air conditioner, and even the phenomenon that the water source heat pump air conditioner cannot provide heating.
