Abstract

The utility model discloses a novel directly-heated type heat pump hot water unit, comprising a compressor, a condenser and an evaporator which are sequentially connected, wherein an expansion valve used for closure is arranged between the condenser and the evaporator, and the condenser is further connected with a pressure adjusting valve. The utility model has novel structure and high energy-saving and heating efficiency.

Description

Novel directly-heated type heat-pump hot-water unit
Technical field
The utility model relates to field of air conditioning, particularly relates to a kind of directly-heated type heat-pump hot-water unit.
Background technology
At present, the heat-pump hot-water unit on the market adopts circulation heated type heat pump machine mostly, and the efficiency of heating surface of its high temperature section is generally on the low side, and the project installation relative complex.
The utility model content
The purpose of this utility model provides a kind of novel directly-heated type heat-pump hot-water unit, and novel structure is energy-conservation, the efficiency of heating surface is high.
The technical solution of the utility model is: a kind of novel directly-heated type heat-pump hot-water unit, compressor, condenser and evaporimeter that bag pressure links to each other successively, be provided with the expansion valve that is used to dam between described condenser and the evaporimeter, described condenser also is connected with pressure-regulating valve.
The utility model can be done following improvement, and described pressure-regulating valve is located between described compressor and the condenser, and promptly described pressure-regulating valve is installed on the input of described condenser.
The beneficial effects of the utility model are:
(1) a kind of novel directly-heated type heat-pump hot-water unit of the present utility model, when heat pump, by regulating the condensing pressure of condenser, the adjusting of the current size that realizes intaking, thereby guarantee that from the water that condenser comes out be 55 degree hot water, this hot water is directly put as for standby in the attemperater.
(2) a kind of novel directly-heated type heat-pump hot-water unit of the present utility model, novel structure, energy-conservation, the efficiency of heating surface is high, project installation is simple.
Description of drawings
Fig. 1 is the operation principle schematic diagram of the utility model embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of novel directly-heated type heat-pump hot-water unit shown in Figure 1 is the specific embodiment of the present utility model, compressor 1, condenser 2 and evaporimeter 3 that its bag pressure links to each other successively, be provided with the expansion valve 4 that is used to dam between condenser 2 and the evaporimeter 3, condenser 2 also is connected with pressure-regulating valve 5.Pressure-regulating valve 5 is located between compressor 1 and the condenser 2, and promptly pressure-regulating valve 5 is installed on the input of condenser 2, is used to regulate the condensing pressure of condenser 2.
Hot water working principle of said set of the present utility model is as follows: when starting heat pump, regulate the condensing pressure of condenser 2 by pressure-regulating valve 5, and then the size of regulating its water inlet current, to guarantee that from the hot water that condenser 2 comes out be 55 degree, this hot water is directly put as for standby in the attemperater.
The above embodiments only are preferred embodiment of the present utility model, can not limit interest field of the present utility model with this, and therefore, the equivalent variations according to the utility model claim is done still belongs to the scope that the utility model is contained.
