Embodiment Construction

[0077] Examples, see figure 1 and figure 2 Shown: an integrated dual-cooling heat pump unit, including a cooling and / or heating cycle system. The integrated double-cooling heat pump unit may include a refrigeration cycle system alone, or have a heating cycle system alone, or have both refrigeration and heating cycle systems. Specifically, the integrated dual-cooling heat pump unit includes a compressor 1, an oil separator 2, an air-cooled heat exchanger 3, a double-cooling condenser 4, a bidirectional expansion and throttling device 6, and a user-side heat exchange unit connected in series. device7. The air-cooled heat exchanger 3 necessarily has a heat exchange fan 10 .

[0078] in:

[0079] The refrigeration cycle system is: the exhaust port of the compressor 1 is connected to the air inlet of the oil separator 2, and the exhaust port of the oil separator 2 passes through a third valve 24, the air-cooled heat exchanger 3 1. A fourth electromagnetic valve 31 is connecte...

Abstract

The invention discloses an integrated dual refrigerating and heating pump unit. The integrated dual refrigerating and heating pump unit comprises a refrigerating and / or heating circulating system, wherein the refrigerating and / or heating circulating system comprises a compressor, an oil separator, an air-cooled heat exchanger, a dual-refrigeration condenser, a bi-directional expansion throttling device and a user-side heat exchanger. Due to the fact that the dual-refrigeration condenser, the air-cooled heat exchanger, refrigerating and / or heating circulating, a freeze water hydraulic system, a water disposing system and a centralized control system are integrated into a whole, the integrated dual refrigerating and heating pump unit has the advantages of compact structure, high efficiency, energy conservation, convenience in mounting and maintenance and low manufacturing cost; meanwhile, the problems of effect to heating capacity and high power caused when the air-cooled heat exchanger is defrosted during heating in winter are solved, power consumption during defrosting is low, the defrosting time is short, water can be timely removed, and heating is restored as soon as possible.

Description

technical field [0001] The invention relates to the technical field of air conditioning units, in particular to an integrated double cooling and heat pump unit. Background technique [0002] At present, the integrated heat pump unit on the market is a combination of conventional chiller, evaporative condenser, air-cooled heat exchanger, four-way reversing valve, cooling pump, pipeline and control device. When heating in winter, the air-cooled heat exchanger is used as the evaporator through the four-way reversing valve. When the outside temperature is too low, frost will form on the surface of the air-cooled heat exchanger, reducing the heat exchange effect, resulting in a decrease in heating capacity, and even the unit cannot be started normally. At this time, it is necessary to defrost in reverse cycle through the four-way valve. In this way, instead of providing heat to the room, it will absorb heat from the room, affecting the heating operation efficiency, resulting in...
