Abstract
Disclosed is a modularization high temperature water source heat pump unit, comprising a condenser, a thermostatic expansion valve, and an evaporator. An octagon semi-hermetic piston compressor is arranged on the evaporator, large-capacity tube heat exchangers are respectively installed in the evaporator and the condenser. Spiral casing tubes of inner spiral tubes are arranged in mutually independent upper and lower internal parts of the tube heat exchanger with large-capacity; water input tubes at both ends of the spiral casing tubes are connected with a same three-way tube, while the water output tubes are connected with another three-way tube. The utility model has small volume, high temperature of output water and large heat exchange area but also can improve anti-freezing performance.
Description
Affiliated technical field
The utility model relates to compression heat pump systems technology field.
Background technology
Water source heat pump units is used more and more widely as a kind of novel source pump.The cold-producing medium circulation power of this source pump derives from compressor, for the bigger water source heat pump units of capacity, compressor adopts semiclosed screw rod pattern mostly, this compressor lubrication system complexity, part processing precision requires high, and volume is big, and the modulability under sub-load is relatively poor, when 60% following load operation, coefficient of performance COP sharply descends especially.And the evaporimeter of this source pump and condenser be shell and tube exchanger mostly, and heat transfer coefficient is little, and heat exchange efficiency is low, complex structure, and the production cost height, and heat-transfer effect is not good enough.
Summary of the invention
The purpose of this utility model is exactly at the deficiencies in the prior art, provides a kind of volume little, simple in structure, the modularization heat pump of high-temp water source unit that heat exchange efficiency is high.
For achieving the above object, the technical solution adopted in the utility model is: it comprises support and casing, the condenser that is installed on the support is arranged in casing, heating power expansion valve and evaporimeter are installed above condenser, compressor is installed above the evaporimeter, compressor outlet is connected with condenser inlet, and compressor inlet is connected with evaporator outlet.Said compressor adopts anistree semiclosed piston compressor.In evaporimeter and condenser, be separately installed with big capacity double-tube heat exchanger, said big capacity double-tube heat exchanger comprises that upper and lower two separate inside are equipped with the screw shell of pipe in the spiral, the water inlet pipe of two screw shell ends is connected on the same three-way pipe, and the outlet pipe of two screw shell ends is connected on another three-way pipe.
The utility model adopts anistree semiclosed piston compressor, has improved the compression ratio of unit, thereby has improved the unit leaving water temperature, and the shortcoming that coefficient of performance COP sharply descends when having overcome operation at part load has reduced volume, has saved material, has reduced cost.Big capacity double-tube heat exchanger is guaranteeing to have increased heat exchange area under the certain situation of refrigerant system resistance, thereby has improved unit refrigeration (heating) amount, has improved heat exchange efficiency, and can improve resistance to deformation and the freeze proof ability of splitting.
Description of drawings
Fig. 1 is a front view of the present utility model, shows its overall structure;
Fig. 2 is the front view of big capacity double-tube heat exchanger.
The specific embodiment
In the embodiment shown in the figures, the utility model comprises support 1 and the casing 10 that is connected with support 1.Condenser 2, heating power expansion valve, evaporimeter 3 and compressor 4 are installed in casing 10, and each parts links together by copper pipe.Condenser 2 is installed on the support 1, and evaporimeter 3 is installed in above the condenser 2 by bolt, anistree semiclosed piston compressor 4 be installed in evaporimeter 3 above.Compressor 4 outlets are connected with condenser 2 imports, and compressor 4 imports are connected with evaporimeter 3 outlets.In evaporimeter 3 and condenser 2, be separately installed with big capacity double-tube heat exchanger, said big capacity double-tube heat exchanger comprises that upper and lower two separate inside are equipped with the screw shell 7,6 of pipe 5 in the spiral, the water inlet pipe of two screw shell ends is connected on the same three-way pipe 8, and the outlet pipe of two screw shell ends is connected on another three-way pipe 9.The helical angle of pipe 5 is the 10-45 degree in the spiral in the screw shell, is evenly distributed in the shell and coaxial with shell.
