Abstract
A full thermal recovery screw rod type heat pump machine unit relates to the technical field of the air conditioner refrigeration. The invention comprises an air conditioner refrigeration system composed of a screw rod compressor, a condenser, a heating power expansion valve and an evaporator, the structure has characteristic that the condenser is a double-tube bundle casing condenser. The invention not only can simplify the refrigerant system, but also can omit the control for the refrigerant flow path, and has characteristics that the control is simple and the cost can be saved.
Description
Technical field
The present invention relates to the air conditioner refrigerating technical field, particularly full thermal recovery screw rod type heat pump machine unit.
Background technology
Characteristics such as screw rod type heat pump machine unit is big owing to its refrigerating capacity, fault rate is low are widely used in the air-conditioning system of building.How improving utilization efficiency of energy and reach purpose of energy saving, is present subject matter.Condensation waste heat when reclaiming refrigeration is used to produce the domestic hot-water, is undoubtedly best settling mode.
The recuperation of heat of screw rod type heat pump machine unit is divided into portion of hot and reclaims and full recuperation of heat.Portion of hot reclaims the main sensible heat part that reclaims the cold-producing medium exhaust, is the net quantity of heat that sensible heat adds latent heat and full recuperation of heat is reclaimed, and obviously full recuperation of heat is more energy-conservation.
In the prior art, the unit of full heat recovery system generally will adopt two condensers to realize that one is cooling water system, and another is used for recovery waste heat.Realize full recuperation of heat by the control refrigerant flow direction.Obviously utilize more than two condenser cost height, the material usage and refrigerant flow path control complexity.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the purpose of this invention is to provide a kind of full thermal recovery screw rod type heat pump machine unit.It not only can simplify refrigerant system, has also omitted the control to refrigerant flow path simultaneously, has the advantages that control is simple, save cost.
In order to reach the foregoing invention purpose, technical scheme of the present invention realizes as follows:
A kind of full thermal recovery screw rod type heat pump machine unit, it comprises the air-conditioning refrigeration system of being made up of helical-lobe compressor, condenser, heating power expansion valve, evaporimeter.Its design feature is that described condenser is a double-tube bundle case condenser.
In above-mentioned screw rod type heat pump machine unit, described condenser comprises housing, the refrigerant loop of forming by refrigerant inlet, refrigerant outlet, the cooling water of being made up of cooling water inlet, coolant outlet in the housing reclaims the heat recovery water loop of being made up of heat recovery water import, heat recovery water outlet in loop and the housing.
The present invention uses a double-tube bundle case condenser owing to adopted said structure, has simplified refrigerant system.A public refrigerant side has omitted the control to refrigerant flow path in the condenser.The present invention has simplified system pipeline, has reduced the trouble point of refrigeration system, has reduced the cost of source pump.
The present invention will be further described below in conjunction with the drawings and specific embodiments
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of double-tube bundle case condenser among the present invention.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the present invention includes the air-conditioning refrigeration system of forming by helical-lobe compressor 1, double-tube bundle case condenser 3, heating power expansion valve 4, evaporimeter 2.Condenser 3 comprises housing 32, the refrigerant loop of forming by refrigerant inlet 31, refrigerant outlet 37, the cooling water of being made up of cooling water inlet 36, coolant outlet 33 in the housing 32 reclaims in loop and the housing 32 by heat recovery water import 35, the heat recovery water outlet 34 heat recovery water loops of forming.
There are two current roads double-tube bundle case condenser 3 inside of unit of the present invention, and one is used for cooling water, and another is used for recuperation of heat.Two tube banks are present in the same housing, a public refrigerant side.Realize full recuperation of heat by control: open the heat recovery water loop when hot water demand is arranged and carry out Waste Heat Recovery to the water route; Open cooling water during no hot water demand and reclaim the loop.Two states all provides the chilled water of air-conditioning simultaneously.
