Abstract
Description
本発明は室外機の冷凍サイクル用配管に温度センサーを固定した空気調和機に関するものである。 The present invention relates to an air conditioner in which a temperature sensor is fixed to a pipe for a refrigeration cycle of an outdoor unit.
従来、空気調和機の室外機の冷凍サイクル用配管を流れる冷媒の温度を測定するために、温度センサーを配管に板バネ保持具を用いて密着固定していた。（例えば、特許文献１参照）。 Conventionally, in order to measure the temperature of the refrigerant flowing through the refrigeration cycle pipe of the outdoor unit of the air conditioner, the temperature sensor is tightly fixed to the pipe using a leaf spring holder. (For example, refer to Patent Document 1).
図５は、特許文献１に記載された従来の温度センサーを冷凍サイクル用配管に固定する手順を示した断面図を示すものである。図５に示すように、外郭ケースが種々の金属製である温度センサー５２を、まず金属製の板バネ保持具５３の右端に嵌め込んで装着固定し、板バネ保持具５３と温度センサー５２が一体になったものを配管５１に嵌め込んで装着固定することで、配管５１と温度センサー５２を密着固定していた。 FIG. 5 is a cross-sectional view showing a procedure for fixing the conventional temperature sensor described in Patent Document 1 to the piping for the refrigeration cycle. As shown in FIG. 5, a temperature sensor 52 whose outer case is made of various metals is first fitted into the right end of a metal leaf spring holder 53 and fixed, and the leaf spring holder 53 and the temperature sensor 52 are connected to each other. The pipe 51 and the temperature sensor 52 are fixed in close contact by fitting and fixing the integrated body into the pipe 51.
しかしながら、冷凍サイクル用配管がアルミニウム製（アルミニウム合金も含む）の場合、アルミニウム製配管の腐食を防止するため、温度センサーの外郭金属ケースもアルミニウム製（アルミニウム合金も含む）にするのが好ましい。しかしながら板バネ保持具は通常ステンレス製のため、アルミニウム製配管とアルミニウムケース製温度センサーを、そのままステンレス製板バネ保持具で固定すると、異種金属接触によりアルミニウム製配管やアルミニウムケース製温度センサーが腐食するという課題があった。 However, when the piping for the refrigeration cycle is made of aluminum (including aluminum alloy), it is preferable that the outer metal case of the temperature sensor is also made of aluminum (including aluminum alloy) in order to prevent corrosion of the aluminum piping. However, since the plate spring holder is usually made of stainless steel, if the aluminum pipe and the aluminum case temperature sensor are fixed directly with the stainless steel plate spring holder, the aluminum pipe and the aluminum case temperature sensor will corrode due to contact with different metals. There was a problem.
本発明は、前記従来の課題を解決するもので、アルミニウム製配管およびアルミニウムケース製温度センサーを、ステンレス製板バネ保持具を用いて固定しても、異種金属接触による腐食を防止することができる空気調和機を提供することを目的としている。 The present invention solves the above-described conventional problems, and even when an aluminum pipe and an aluminum case temperature sensor are fixed using a stainless steel plate spring holder, corrosion due to contact with different metals can be prevented. The purpose is to provide an air conditioner.
前記従来の課題を解決するために、本発明の空気調和機は、室外機の冷凍サイクル用配管をアルミニウム製（アルミニウム合金も含む）とし、前記配管に密着固定し前記配管内を流れる冷媒の温度を計測する温度センサーの外郭ケースもアルミニウム製（アルミニウム合金も含む）とした、空気調和機において、前記温度センサーを前記配管に密着固定するステンレス製板バネ保持具の表面に塗装を施したものである。 In order to solve the above-described conventional problems, the air conditioner of the present invention is configured such that the refrigeration cycle pipe of the outdoor unit is made of aluminum (including an aluminum alloy), and the temperature of the refrigerant flowing in the pipe is fixedly fixed to the pipe. In the air conditioner, the outer case of the temperature sensor that measures the temperature is also made of aluminum (including aluminum alloy), and the surface of the stainless steel leaf spring holder that adheres and fixes the temperature sensor to the pipe is painted. is there.
これにより、アルミニウム製配管およびアルミニウムケース製温度センサーとステンレス板バネ保持具との間が塗装で絶縁されるため、アルミニウム製配管およびアルミニウムケース製温度センサーの腐食を防止することができる。 Accordingly, the aluminum pipe and the aluminum case temperature sensor and the stainless steel leaf spring holder are insulated by the coating, so that the corrosion of the aluminum pipe and the aluminum case temperature sensor can be prevented.
本発明の空気調和機は、アルミニウムケース製温度センサーを、ステンレス製板バネ保持具を用いてアルミニウム製配管に密着固定しても、アルミニウムケース製温度センサーおよびアルミニウム製配管の腐食を防止することができ、空気調和機の室外機の信頼性を
向上することができる。
The air conditioner of the present invention can prevent corrosion of the aluminum case temperature sensor and the aluminum pipe even if the aluminum case temperature sensor is firmly fixed to the aluminum pipe using the stainless steel leaf spring holder. The reliability of the outdoor unit of the air conditioner can be improved.
第１の発明は、室外機の冷凍サイクル用配管をアルミニウム製（アルミニウム合金も含む）とし、前記配管に密着固定し前記配管内を流れる冷媒の温度を計測する温度センサーの外郭ケースもアルミニウム製（アルミニウム合金も含む）とした、空気調和機において、前記温度センサーを前記配管に密着固定するステンレス製板バネ保持具の表面に塗装を施したことにより、アルミニウム製配管およびアルミニウムケース製温度センサーとステンレス板バネ保持具との間が塗装で絶縁されるため、アルミニウム製配管およびアルミニウムケース製温度センサーの腐食を防止することができる。 According to a first aspect of the present invention, the refrigeration cycle pipe of the outdoor unit is made of aluminum (including an aluminum alloy), and the outer case of the temperature sensor for measuring the temperature of the refrigerant flowing in the pipe in close contact with the pipe is also made of aluminum ( In an air conditioner that includes an aluminum alloy), the surface of a stainless steel leaf spring holder that tightly fixes the temperature sensor to the pipe is coated, so that the aluminum pipe and the aluminum case temperature sensor and stainless steel are coated. Since the space between the leaf spring holder and the plate spring is insulated by coating, corrosion of the aluminum pipe and the aluminum case temperature sensor can be prevented.
第２の発明は、室外機の冷凍サイクル用配管をアルミニウム製（アルミニウム合金も含む）とし、前記配管に密着固定し前記配管内を流れる冷媒の温度を計測する温度センサーの外郭ケースもアルミニウム製（アルミニウム合金も含む）とした、空気調和機において、
前記温度センサーを前記配管に密着固定するステンレス製板バネ保持具の内側に絶縁シートを配したことにより、アルミニウム製配管およびアルミニウムケース製温度センサーとステンレス板バネ保持具との間が絶縁シートで絶縁されるため、アルミニウム製配管およびアルミニウムケース製温度センサーの腐食を防止することができる。
According to a second aspect of the present invention, the refrigeration cycle pipe of the outdoor unit is made of aluminum (including an aluminum alloy), and the outer case of the temperature sensor for measuring the temperature of the refrigerant flowing in the pipe in close contact with the pipe is also made of aluminum ( In the air conditioner, including aluminum alloys)
The insulation sheet is insulated between the aluminum pipe and the aluminum case temperature sensor and the stainless steel leaf spring holder by arranging an insulating sheet inside the stainless steel leaf spring holder that tightly fixes the temperature sensor to the pipe. Therefore, corrosion of the aluminum pipe and the aluminum case temperature sensor can be prevented.
以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.
