Double-compressor cold water heat pump unit

Abstract

The invention relates to the technical field of heat pump units, and discloses a double-compressor cold water heat pump unit. The double-compressor cold water heat pump unit comprises double compressors, an evaporator, a condenser and a throttling valve, wherein cooling fins are arranged at the lower end of the condenser, four sets of cushioning mechanisms are fixedly arranged at the lower ends ofthe cooling fins, a cooling device is arranged on the outer side of the bottom of the cushioning mechanisms, a rain collecting device is arranged above the interior of a heat dissipation pool, a dirtremoving mechanism is arranged at the front end of the cooling device and the interior of the cooling device, and spraying devices are connected to the positions, located in front of and behind the condenser, in the cooling device; and the cooling device comprises the heat dissipation pool, a water discharging pipe and fans, the water discharging pipe is fixedly arranged on one side of the upperend of the heat dissipation pool, and the four sets of fans are arranged at the corners of the top of the inner side of the heat dissipation pool. According to the double-compressor cold water heat pump unit, the effect of buffering and protecting the heat pump unit can be achieved, the service life of the heat pump unit is prolonged, and the noise generated by the heat pump unit is reduced.

Description

technical field [0001] The invention relates to the technical field of heat pump units, in particular to a dual-compressor cold water heat pump unit. Background technique [0002] A heat pump is a high-efficiency energy-saving device that makes full use of low-grade heat energy. Heat can be spontaneously transferred from a high-temperature object to a low-temperature object, but it cannot be spontaneously carried out in the opposite direction. The working principle of the heat pump is to force heat from a low temperature to The mechanical device in which objects flow to high-temperature objects consumes only a small amount of reverse cycle net work to obtain a large amount of heat supply, and can effectively utilize low-grade heat energy that is difficult to apply to achieve energy-saving purposes. [0003] It generally consists of four parts: compressor, condenser, throttle valve, and evaporator. For example, air at normal temperature) absorbs heat and vaporizes into low-p...

Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides a dual-compressor cold water heat pump unit, which has a better heat dissipation effect of the heat pump unit, can play a role of buffer protection for the heat pump unit, increases the service life of the heat pump unit, and reduces the generation of heat pump units. It solves the problem that the traditional outdoor heat pump unit dissipates heat through the fan, and the heat dissipation performance is poor. The vibration phenomenon of the heat pump unit is relatively serious during the working process. After long-term use, the internal parts of the heat pump unit are easily damaged. Installed in residential areas The heat pump unit will generate noise during the vibration process, and the noise is not easy to eliminate, causing the problem of noise pollution
